Vascularization of the shoulder and forearm of the big gray goose

Abstract

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.
