They supply sensory, motor, and secretomotor supply to the esophagus. This pattern of supply is characteristic of the entire esophagus [3,10,16]. More specifically, it can refer to: Esophageal branches of inferior thyroid artery (top third) Kenhub. 1991;142(3):204-7. Oral cavity -> mediastinum -> right crus of diaphragm -> stomach, Esophageal branches of the thoracic aorta, azygos, hemiazygos, accessory hemiazygos veins, Inferior deep cervical, posterior mediastinal, intercostal, paratracheal, superior and inferior tracheobronchial lymph nodes, Those supplying the cervical part originate from the, The abdominal part is supplied by arteries from the, Veins from the cervical part drain into the, The thoracic part is drained by veins that flow into the, The vessels from the abdominal part open into the, Esophagus (anterior view) - Begoña Rodriguez, Esophagus in situ (anterior view) - Yousun Koh, Arteries of the esophagus (anterior view) - Yousun Koh, Veins of the esophagus (anterior view) - Yousun Koh, Nerves of the esophagus (anterior view) - Yousun Koh, Neck viscera (cadaveric dissection) - Prof. Carlos Suárez-Quian. Gullet 1992;2:3-10. The vessels of both sides are "joined by anastomotic twigs along the trachea [10]" and divide into three to four tracheal branches with two to three tributaries to the esophagus, which in turn subdivide within the periesophageal tissue into vessels of less than 500 µm luminal diameter, before entering the esophageal wall. METHODOLOGY: Esophageal stumps of five groups of rabbits were studied. When food or liquids are transported by peristaltic waves and approach the sphincters, reflex pathways cause the muscles to temporarily relax and open, allowing the bolus to pass. BACKGROUND/AIMS: The purpose of the study was to determine the blood supply of stumps of mobilized esophagus. Akiyama H. Surgery for carcinoma of the esophagus. The esophagus measured from the cricoid cartilage and cardiac notch, ranged from 21 to 34 cm (average of 27 cm) in 52 corpses in accordance with the height of the body (153 to 187 cm). Swenson O, Merrill K, Pierce EC, Rheinlander HF. Kim Bengochea, Regis University, Denver, Author: Gastroenterology 1984;86:866-875. The esophagus is divided into three parts: As you might have guessed, the esophagus doesn’t simply float in mid-air. It can get quite confusing, right? Esophagectomy without thoracotomy: a dangerous operation? Reviewer: Evaluations of previous workers were largely based on dissection specimens using a more or less coarse injection material. The venous system (venules and veins) is filled by retrograde infusion and is also displayed. During their course the transverse vessels subdivide into multiple fine branches throughout the submucosa. The arteries supplying the esophagus are generally named ‘esophageal arteries’. They give off vessels of 200-300 µm in diameter at right angles that pass around the circumference, in a circular manner, to anastomose with the vessels of the opposite site. Surg Gynecol Obstet 1950;90:234-243. The casts display the multidimensional arrangement of the extramural and intramural esophageal blood vessels [3,8]. The trachea and esophagus travel closely together through the neck, with the vertebral column situated posterior to the esophagus. Ann Surg 1950;131:171-185. While in the lower thoracic portion, the greater thoracic splanchnic nerves are important. As you know, you cannot purposefully control your esophagus, hence it is under involuntary control by the autonomic nervous system. Reading time: 7 minutes. J Thoracic Surg 1950;19:462-476. Introduction to the musculoskeletal system, Nerves, vessels and lymphatics of the abdomen. 2021 1) run straight up for 4-6 cm, within the periesophageal tissue. At variable distances they give off small tributaries of less than 500 µm internal diameter before they penetrate the esophageal wall [3,15]. The esophageal … Copyright © The blood of both the cranial trachea and cervical esophagus is mainly provided by the inferior thyroid arteries [3,10-13] each giving off a 2 to 3 cm long branch called the tracheoesophageal artery, that travels on each side towards caudal and medial to approach the tracheoesophageal grove. Thoracic portion of esophagus takes blood flow from aorta, bronchial arteries, and right intercostal arteries. Alexandra Osika The intrathoracic esophagus receives blood from two origins (Figs. 4. 1. The foregut gives rise to the esophagus, stomach, and the first and second parts of the duodenum, as well as the liver, gallbladder, and superior part of the pancreas. There you will also find a special quiz about the esophagus anatomy which covers the structure, blood supply and nerves of the esophagus! Adrian Rad BSc (Hons) Gross anatomy. At all other times, these sphincters are fully contracted and closed in order to prevent the reflux of food particles or gastric acid into previous segments of the digestive tract. Esophagus. Blood supply: Esophageal branches of the thoracic aorta, azygos, hemiazygos, accessory hemiazygos veins: Lymphatics: Inferior deep cervical, posterior mediastinal, intercostal, paratracheal, superior and inferior tracheobronchial lymph nodes: Histology: Mucosa: nonkeratinized stratified squamous epithelium, lamina propria, smooth muscle layers Submucosa: esophageal glands and … Anastomotic failures practically always arise from the visceral substitute. Its parasympathetic innervation arises from the thoracic esophageal nervous plexus, while its sympathetic component originates from the fifth to twelfth thoracic spinal nerves (T5-T12). All the organs derived from the foregut are supplied by the branches of the celiac trunk (artery). 10. A study on blood supply of the esophagus. Their respective characteristically different endothelial (nuclear) impressions allow a ready distinction. D. Liebermann-Meffert, M. Allgower, JR. Siewert (Munich). Blood and nerve supply to the esophagus: an experimental study. Inferior thyroid artery supplies arterial blood flow to cervical portion of esophagus (Figure 6). Williams DB, Payne WS. Via a tightly regulated interplay between the parasympathetic and sympathetic branches, the tone of the esophageal sphincters is maintained, their transitory relaxation is permitted, and peristalsis along the entire esophagus takes place. Blood Drainage The esophageal veins from the upper third drain in into the inferior thyroid veins. During their course the transverse vessels subdivide into multiple fine branches throughout the submucosa. The bronchoesophageal artery is the main source of blood for the cranial two thirds of the thoracic esophagus; the remaining thoracic esophagus is supplied by esophageal branches of the aorta or dorsal intercostal arteries. Email this page; Link this page ; Print; Please describe! PMID: 1796734 Abstract In accordance with former authors the arteries for the cervical esophagus originate mainly from the inferior thyroid artery. It was 23 cm ± 2 SD in the female and 28 cm ± 3 SD in the male. It actively facilitates the passage of the food bolus into the stomach under precise nervous regulation. Neglecting the striking species differences in the vascular anatomy [3,8], results from experiments using animals were included which also produced apparent confusion in the various descriptions. Bull Ass Anat 1976;60:489-496. An anatomic study of 150 specimens. Vallee B, Hong R, Renelier B, Person H, Huu N. Les artères oesophagiennes d'origine cervicale. The esophageal vascular casts provide the morphological basis for circulation. 14. In contrast to the previous two, the abdominal part of the esophagus is slightly different. Throughout its course, it is closely related with many structures. Blood Supply of Esophagus Variant Image ID: 49410 Add to Lightbox. They differ according to the vessels into which they flow: If you want to learn more about the blood supply of the esophagus and master esophageal arteries and veins, take a look at the following resources! The cervical esophagus receives its blood supply predominantly from the cranial and caudal thyroid arteries together with smaller branches from the carotid arteries. Affiliation 1 Institut für Anatomie, Universität Wien, Osterreich. Nevertheless, the surgically mobilized esophagus retained viability over a long distance when carefully handled [4-7]. Register now The parasympathetic component of the plexus originates from the vagus nerve, while the sympathetic fibers also stem from the sympathetic trunk running along the neck. The cervical esophagus is supplied via the paired superior and inferior thyroid arteries (Figs. In this page we’ll learn more about this control, as well as the anatomy, sphincters, blood supply, and innervation of the esophagus. Variants, such as branches from intercostal arteries (if there are any) [3,8,11], seem to be insignificant for the blood supply of the human esophagus. 6. Size out of scale. Orringer MB, Orringer JS. The extent to which one may interfere with the blood supply of the esophagus and obtain healing on anastomosis. Figure 1. “I would honestly say that Kenhub cut my study time in half.” how you will use this image and then you will be able to add this image to your shopping basket. What are the characteristics of the normal blood supply of the esophagus? In turn, the gastroesophageal junction is surrounded by the lower esophageal sphincter, also known as the cardiac sphincter. The blood supply of the cervical esophagus is derived from the inferior thyroid artery, while the blood supply for the thoracic esophagus comes from the bronchial arteries and the aorta. If you want to find out more about the intricate innervation of the esophagus, simply take a sneak peek below! Ok. The esophagus is 23-37 cm long with a diameter of 1-2 cm and is divided into three parts: cervical: continuous with the hypopharynx, commences at the lower border of cricoid cartilage (at level of C5/6) or cricopharyngeus muscle; thoracic: from superior thoracic aperture (T1) to the esophageal hiatus (T10) in the diaphragm which covers the inferior thoracic aperture The esophagus is supplied by both parasympathetic and sympathetic fibres. The majority of esophageal branches arise from the terminal branches of this artery; its ascending and descending portions frequently give rise to one or more esophageal branches. The remarkably low blood loss during the procedure and the frequency of postoperative anastomotic leaks suggested a primarily poor esophageal vascularization. The pharyngoesophageal junction is surrounded by the upper esophageal sphincter, also known as the cricopharyngeus muscle. The esophagus is about 9-10 inches (25 centimeters) long and less than an inch (2 centimeters) in diameter when relaxed. Ann Surg 1987;206:184-192. Last reviewed: February 27, 2021 The esophagus (American English) or oesophagus (British English; see spelling differences) (/ɪˈsɒfəɡəs/), informally known as the food pipe or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The increasing range of operative procedures for diverticula, stenosis and malignancy of the esophagus, problems arising with leaking esophageal anastomoses and the supposition that the integrity of the anastomosis and the viability of the organ depends on an intact circulation required an accurate consideration of the related vascular anatomy. The stellate ganglia provide smaller nerve fibers, known as the ansae subclavia, that supply the thoracic esophagus. Read more. Esophageal branches from the inferior thyroid artery (from the thyrocervical trunk) provide the cervical part's arterial blood supply. These branches ascend as an anterior and posterior branch beneath the visceral peritoneum to supply perforating branches to the intramural and submucosal plexuses. Through the action of both skeletal and smooth muscle fibers, the esophagus is capable of creating waves of peristalsis that actively push the contents down the digestive system. 3. The absence of tissues around the vascular casts and the ability to examine stereo pairs exclude potential misinterpretation of closely overlaying vessels [3,9]. vessel of direct aortic origin, all others derive from the larger stem vessels of different organs (Fig. Khaleel Alyahya, PhD, MEd. Stomach Anatomy; Arterial Supply of the Stomach; Venous Drainage of the Stomach; Stomach Lymphatic Drainage; Innervation of the Stomach; Small Intestine. The primitive gut is divided into the foregut, midgut, and hindgut. – Their configurational anatomy and variations in relation to surgery. During swallowing, the epiglottistilts backwards to pr… With up to 11 arterial branches the left gastric artery supplies mainly the anterior and right lateral aspect of the esophageal wall, while the splenic artery is the source of blood for mainly the posterior and left lateral aspect (cardiac notch) by either one or two direct branches or via vessels of the gastric fundus including connections with the short gastrics. Esophageal (Oesophageal in British English) arteries are a group of arteries from disparate sources supplying the esophagus. 2. There is no short supplied or avascular zone. The intramural network thus provides a luxurious, although fine vascularity for the esophagus, by a system of small arteries, arterioles and capillaries which nevertheless needs careful surgical handling. 1 and 2). Frequently one bronchoesophageal artery originates 1-3 cm caudal to the vascular bundle from the anterolateral aspect of the descending aorta [3]. The esophagus is a 25-cm long muscular tube that connects the pharynx to the stomach. Read more. The main arterial blood supply to the cervical esophagus is from branches of the cranial and caudal thyroid arteries. Surgery 1950;28:11-23.

Netter; Gastroenterology; Gastrointestinal; Heme; heme and immune systems; Immune; Supply ; Systems; Tract; Upper Gastrointestinal Tract; × Note. Demel R. Die Gefäßversorgung der Speiseröhre. This muscle is actually a portion of the inferior pharyngeal constrictor. 8. - One (or seldom two) unpaired proper esophageal artery with luminal diameter between 1-2 mm may arise more caudally from the anterior aspect of the descending aorta as an exclusive source (Fig. Arch Klin Chir 1924;128:453-504. Learning anatomy is a massive undertaking, and we're here to help you pass with flying colours. The esophageal arteries. [2] Stem vessels are striped, esophageal branches black and the larger intramural vessels dotted. A continuous regular network located in the submucosa connects all the extramural vessels. • Liebermann-Meffert D, Siewert JR. Arterial anatomy of the esophagus. The only difference between them is given by their origins according to the different esophagus divisions: The veins follow a similar logic to the arteries. Neglecting the striking species differences in the vascular anatomy [, thyreocervical trunk of subclavian artery, respectively. Cervical – from the inferior thyroid artery (from the thyrocervical trunk) Thoracic – from the aorta and intercostal arteries [The blood supply of the cervical esophagus] Acta Anat (Basel). The cervical region of the esophagus receives blood from esophageal branches of the inferior thyroid artery. The parasympathetic component of the cervical part is supplied by the recurrent laryngeal nerve (a branch of the vagus nerve (CN X)) while the sympathetic fibers arise from the cervical sympathetic trunk. The arteries may or may not be accompanied by veins. More recently the smaller vessels, and in particular those entering the esophageal wall, could be clearly demonstrated by means of vascular corrosion casts [3]. The blood supply to the esophagus can roughly be divided into thirds, with anastamoses between each area of supply. Arteries of Esophagus Blood Supply of the Esophagus; Arteries of Esophagus Blood Supply of the Esophagus Variant Image ID: 4397 Add to Lightbox. It forms an important piece of the gastrointestinal tract and functions as the conduit for food and liquids that have been swallowed into the pharynx to reach the stomach. 16. Parts of the Small Intestine These give off several small branches to the esophagus which subdivide within the periesophageal tissue to vessels of 350-500 µm in diameter. The blood supply of the esophagus is segmental (see the image below). These observations suggest that there is a rich intramural arterial and venous network complementing the segmental blood supply of the esophagus. Vascular Supply of the Esophagus The three segments of the esophagus are supplied by various arteries. 5. Save to Lightbox. Liebermann-Meffert DM, Luescher U, Neff U, Rüedi TP, Allgöwer M. In transhiatal blunt esophagectomy there is surprisingly little bleeding if no adjacent great vessels are torn. The capillary part revealed a complex polygonal meshwork of vessels that were connected to others, principally of similar diameter. across the diaphragmatic hiatus. Etude anatomique de 23 dissections. Pricing . and grab your free ultimate anatomy study guide! It consists of muscles that run both longitudinally and circularly, entering into the abdominal cavity via the right crus of the diaphragm at the level of the tenth thoracic vertebrae. 7. Curr Probl Surg 1980;17:53-120. The branches from both stem vessels that supply the esophagus (Fig. Since the esophagus is the third section of the gastrointestinal tract, it is connected at either end by other structures, resulting in two junctions: The passage of the food bolus through these junctions is regulated by sphincters; bundles of muscle fibers under involuntary control. All esophagus parts with the arterial blood supply provide esophageal branches from various arteries. After piercing the diaphragm through the esophageal hiatus, the abdominal part continues close to the left lobe of the liver, finally ending in the stomach. 1 and 2), which are described below: - Up to four unpaired tracheobronchial arteries [3,8,11,12,14,15] which derive as a bundle from the inflexion of the aortic arch [3]. The contours provided by the vascular network reflect the esophageal shape. They reproduce the macroscopic features of the esophagus by presenting vessels within the submucosa and down to microscopic dimensions [3]. The inferior thyroid artery supplies the cervical esophagus. According to the dominant size of the extramural vessels, however, it is evident that the cervical and abdominal sources provide the major blood supply to the esophagus, while the small stem vessels at the level of the carina seem to be of minor importance. Surg Gynecol Obstet 1966;123:99-102. Having reduced their diameter by approaching the periesophageal tissue, the extramural vessels pass perpendicularly through the layers of the tunica muscularis, give off a few small tributaries to the muscle bundles en route before they divide at the muscular side of the submucosa into one or two vessels of approximately 400 µm in diameter to follow the longitudinal axis of the esophagus. Shapiro AL, Robillard GL. Gloor F Die Gefäßversorgung der Speiserohre. 1 and 2) which derive from the right and left exterior carotid artery and the. At variable distances they give off small tributaries of less than 500 µm internal diameter before they penetrate the esophageal wall [, Having reduced their diameter by approaching the periesophageal tissue, the extramural vessels pass perpendicularly through the layers of the tunica muscularis, give off a few small tributaries to the muscle bundles en route before they divide at the muscular side of the submucosa into one or two vessels of approximately 400 µm in diameter to follow the longitudinal axis of the esophagus. Gannon B, Browning J, O'Brien P, Rogers P. Mucosal microvascular architecture of the fundus and of human stomach. placed at which ever level. The bronchesophageal artery supplies the majority of the intrathoracic portion, while the terminal portion is vascularized by the esophageal branch of the left gastric artery. Therefore, it is part of the digestive system. Branching subdivides the already primarily small esophageal vessels to be minute in the periesophageal tissue, before entering the wall of the esophagus. The International Foundation for Postgraduate Surgery, Basel, Switzerland lent its support in writing this article. The esophagus is a fibromuscular tube, about 25 cm (10 in) long in adults, which travels behind the trachea and heart, passes through the diaphragm and empties into the uppermost region of the stomach. J Thorac Cardiovasc Surg 1983;85:72-80. Now that we’ve seen the main parts and junctions of the esophagus, it’s time to look at its neurovasculature. All these vessels form an uninterrupted, minute and dense network in the submucosa (Fig. In this area, which relates to the tracheal bifurcation, all the vessels are straight and short (less than 1.5 cm) and form a firm connection between the aorta, trachea and esophagus [3,8,14,15]. It is crucial that the esophagus itself is provided with an excellent blood supply through longitudinally oriented intramural vessels that permit the anastomosis being. blood supply of the native esophagus, the interposition graft must provide its own axial ]llood supply. [1] The length of the esophagus at birth varies between 8 and 10 cm and measures about 19 cm at age 15 years. The esophagus (oesophagus) is a 25 cm long fibromuscular tube extending from the pharynx (C6 level) to the stomach (T11 level). Our engaging videos, interactive quizzes, in-depth articles and HD atlas are here to get you top results faster. [Article in German] Authors D Burger 1 , E Piehslinger. The lower third is supplied by branches of the left gastric artery. Since in anatomy form follows function, it is quite easy to predict the esophagus function – it transports saliva, liquids, and solids all the way to the stomach. The cervical portion was 3-4 cm, the thoracic 20-26 cm and the abdominal 3-6 cm in length. 2) which signifies that the esophagus depends on "a shared vasculature". 2) for the esophagus [3,8,12,14-16]. Scanning electron microscopy of the complete cast revealed a submucosal network of small arteries and arterioles down to capillary diameter. Each esophageal artery originates from … Ann Otolaryngol 1982;99:29-34. The abdominal esophagus and gastric cardia are supplied by the unpaired left gastric artery [3,8,12,14,15] and the splenic artery [3], which derive from the celiac axis (Figs. They, therefore, may undergo contractile hemostasis when torn. 13. For example, the stonmeh interposition graft is based on the gastroepiploie artery (Fig 1). .Scanning electron microscopy of a vascular cast of the human intramural, submucosal blood supply. Arterial sources 2. 2) for the esophagus [, The abdominal esophagus and gastric cardia are supplied by the unpaired left gastric artery [, across the diaphragmatic hiatus. The contribution of the inferior thyroid artery to the blood supply of the human trachea. Besides, surgical experience has clearly shown that problems due to circulatory disturbances are by far, overestimated. Thoraxchirurgie 1953/54;1:146-167. The esophagus is a long, thin, and muscular tube that connects the pharynx (throat) to the stomach. The middle third is supplied by branches of the thoracic aorta. Take note that these are merely the largest and most important related structures. Author information: (1)Department of Surgery, National Cheng Kung University Hospital, Tainan, Taiwan, ROC. This pattern of supply is characteristic of the entire esophagus [. The blood of both the cranial trachea and cervical esophagus is mainly provided by the inferior thyroid arteries [, - Up to four unpaired tracheobronchial arteries [, - One (or seldom two) unpaired proper esophageal artery with luminal diameter between 1-2 mm may arise more caudally from the anterior aspect of the descending aorta as an exclusive source (Fig. Wu MH(1), Sun YN, Huang ST, Chang HY. We reexamined, therefore, the esophageal blood supply in regard to: 1. All rights reserved. .Vessels of organs with which the esophagus shares its characteristic extramural pattern. Esophageal Constrictions; Arterial Supply of the Esophagus; Esophagus Venous Drainage; Lymphatic Drainage of Esophagus; Innervation of Esophagus; Stomach. Figure 3. The microvascular connections are evident in detail after injection of low particle size resin and at a higher magnification. The blood supply of the esophagus is extremely varied. The abdominal esophagus is fed by left gastric artery, short gastric arteries, and descending branch of left phrenic artery. MacManus JE, Dameron JT, Paine JR. Blood supply of esophageal stumps. The thoracic part of the esophagus is innervated by the esophageal plexus, an autonomic nervous network surrounding the esophagus. Several other structures border the esophagus throughout its journey, so here’s an esophageal diagram that provides you with an overview of all of them! Observations on esophageal blood supply. A review of the literature with brief comments on clinical aspects. Grounded on academic literature and research, validated by experts, and trusted by more than 1 million users. The dense continuous network of intramural vessels: structural appearance. An experimental study of the blood supply of the esophagus and its relation to esophageal anastomoses J Thorac Cardiovasc Surg 1950;19:523-533. A general pattern 3. Esophageal arterial blood ow is extremely rich and adequate for anastomosis, but a poor blood supply or careless or over aggressive dissection can cause anastomotic leakage in esophagus … Sources of blood supply to the esophagus concern mainly three areas: from the neck by the paired inferior thyroid arteries; in the chest by the unpaired aortic arch arteries; from the abdomen by the unpaired left gastric and splenic artery. Swigart LVL, Siekert RG, Hambley WC, Anson BJ. If present, this vessel travels obliquely down towards the esophagus within the mediastinum, to divide into a recurrent ascending and a descending branch [12,14]. All together, this vascular intramural network provides a subtle but luxurious vascular supply to the esophagus. The thoracic part passes the great vessels and nerves of the thorax, travelling very closely to the thoracic aorta and azygos vein. thyreocervical trunk of subclavian artery, respectively. 12. 11. 3) to supply the musculature and mucosa. The abdominal oesophagus is supplied by the oesophageal branches of the left gastric artery. Figure 2. Information from the literature was poor and rather confusing. Miura T, Grillo HC. Vascular network in healthy human tissue. The esophagus receives its blood supply from elastic vessels known as arteries that transport blood from the heart. Liebermann-Meffert D, Lüscher U, Neff U, Rüedi ThP, Allgower M. Esophagectomy without thoracotomy: is there a risk of intramediastinal bleeding? Blood Supply The upper third of the esophagus is supplied by the inferior thyroid artery. 9. The esophageal arteries. 15. The blood of both the cranial trachea and cervical esophagus is mainly provided by the inferior thyroid arteries [ 3,10-13] each giving off a 2 to 3 cm long branch called the tracheoesophageal artery, that travels on each side towards caudal and medial to approach the tracheoesophageal grove. One might be concerned about fatal mediastinal bleeding from esophageal vessels, however, "blunt stripping" of the esophagus without thoracotomy for carcinoma has been shown to be relatively safe [1-3]. The parasympathetic fibres are originated from recurrent laryngeal nerves and esophageal plexuses created by vagus nerves. .Standard pattern of the angio-architecture of the esophagus. Save to Lightbox. Shek JL, Prietto CH, Tuttle WM, O'Brien EJ. If you want to learn more about the anatomy of the esophagus, as well as its neighboring structures, take a look at the following resources! Mayo Clin Proc 1982:57:448-453. The short gastric arteries, and occasionally the posterior gastric artery, 1,2 nor- mally supply the distal portion of tlle gastric "tube. The arteries give off short arterioles which display a variety of vessel size (40-20 µm) and break up into capillaries of 5-20 µm in diameter. The obvious viability of these long esophageal segments detached from the segmental blood supply prompted us to preserve and use them in reconstruction. The submucosal vasculature connects the extramural vessels with the intramural vessels in the esophagus without any visible segmental demarcation. Ein Beitrag zur Oesophaguschirurgie. They give off vessels of 200-300 µm in diameter at right angles that pass around the circumference, in a circular manner, to anastomose with the vessels of the opposite site. Evaluations of previous workers were largely based on dissection specimens using a more or less coarse injection material.
