“…Для достижения поставленной задачи использовали комплекс традиционных анатомических методов исследования: тонкое анатомическое препарирование под контролем стереоскопического микроскопа МБС-10, вазорентгенография, измерение диаметра вен с помощью компьютерной программы RadiAnt-2021.2.2-Setup. При описании анатомических терминов использовали Международную ветеринарную анатомическую номенклатуру [9][10][11].…”

When keeping fur-bearing animals, it is necessary to take into account that these animals have increased motor activity when they are in natural biogeocinosis. Due to the fact that these representatives of fur-bearing animals are kept in conditions of inactivity, this can inevitably lead to changes in the structure of the cardiovascular system. The purpose of the study is to study the features of the course and branching of extraorgan veins of the organs of urination in Arctic foxes, to determine the morphometric data of these vessels. The objects for this study were the corpses of female arctic foxes of two age groups: newborns and three to four months, five in each group. To achieve this task, a set of traditional anatomical research methods was used. According to the results of the study, it was found that the course and branching of the extraorgan vessels of the organs of urination in female arctic foxes is different. The main outflow of blood from the kidneys are the right and left renal veins; from the ureter – the cranial and caudal branches of the ureter; from the tip of the bladder – the cranial cystic vein; from the body and the bottom of the bladder is the caudal cystic vein. It is also necessary to note the close relationship of the organs of urination with the reproductive system, since the left renal vein communicates with the ovarian. In addition, we have established the presence of rare valves in the veins of the ureters and bladder, and the absence of such in the vessels of the kidneys. Thus, based on linear parameters, it can be concluded that the diameter of the veins gradually increases with the growth of the animal, especially by the period of maturation and intensification of organs.

“…Тонкая кишка служит местом окончательного переваривания корма. В ней происходит пристеночное пищеварение, а также избирательное всасывание продуктов расщепления белков, углеводов и жиров в кровеносное и лимфатическое русло [1,4,5]. Выполняемые тонкой кишкой функции находят свое отражение в специфики ее гистологической организации [3,7].…”

The material for the study was fragments of the wall of the duodenum, jejunum and ileum obtained from five piglets at the age of 41 days. The selected tissue samples were fixed during the day in a 10.0% solution of neutral formalin. Their further processing in order to obtain histological sections was carried out according to a generally accepted method. The obtained histological sections were stained with hematoxylin and eosin and according to Van Gieson. All morphometric data obtained were subjected to statistical processing.It was found that in the studied animals, the small intestine is arranged in accordance with the general plan of structure peculiar to mammals. Its wall is formed by the mucous membrane, submucosal base, as well as muscle and serous mem-branes. The epithelial layer of the mucous membrane of the small intestine is represented by a single-layer prismatic epithelium, which is a highly dynamic structure that quickly reacts to changing loads due to the high rate of cell renewal. The bulk of the epithelial layer is represented by edged enterocytes (about 90.0% of the entire cell population). In addition to them, goblet-shaped, endocrine, Panethovian, proliferating and stem cells take part in the formation of the epithelial lining of the small intestine.

“…Причем, первая из них является ветвью левой венечной артерии, а вторая -правой. Таким образом, получается, что в независимости от типа кровоснабжения сердца у животных по литературным данным отечественных и зарубежных авторов паракональная артерия всегда принадлежит левой венечной артерии, а субсинуозная артерия -правой [1,5].…”

Goose wings are organs that serve for flying or soaring in the air, they have a powerful muscular system that needs constant blood supply. Arterial blood flows from the heart to the tissues through the arteries, which in turn are divided into arterioles to distribute blood through the tissues of the wing. On the wing of the goose there are flight feathers, without which flight would not be possible. For the growth and development of the feather, a good vascularization of the thoracic limb of this bird is also required. Knowing this, it can be assumed that the vessels going to the wing have a large diameter and a convenient skeletotopic arrangement for various veterinary manipulations during treatment and multiple preventive measures. We decided to set a goal – to study the vascularization of the shoulder and forearm on the example of a large gray goose, as well as to perform morphometry of the main arteries, to study their course and branching. The research was conducted at the Department of Animal Anatomy of the SPbGUVM. The corpses of a large gray goose in the amount of six pieces, aged from 7 to 9 months, were used as material. The corpses of the birds were delivered from a private farm in the Gatchina district of the Leningrad region. Studies of vascularization of the shoulder and forearm of a large gray goose were carried out using a complex of classical and modern research methods used in morphology. As a result of the study, it was found that the arteries of the thoracic limb of a large gray goose include the subclavian, pterygeal, axillary (axillary), scapular, brachial, which, separating, gives the radial and ulnar, deep artery of the shoulder, cranial circumference artery of the shoulder.
