COMPARATIVE ASPECTS OF THE HISTOSTRUСTURAL ORGANIZATION OF SOME MAMMALS UTERUS BODY AND NECK DIFFERENT TYPES

The purpose of the research is improving the efficiency of diagnosis and treatment of reproductive system anomalies by identifying features of the histogenesis and definitive structure of the uterus caudal division tissue components in mammals. By light microscopy rat, rabbit and cat uterus histostructural organization was verified at its caudal part. It was found that in the rat and rabbit uterus wall of the right and left horn coalesce, forming a double body and a neck whose cavities are separated by a thin wall and opens into the vagina two separate holes. Thus, these types of rodents, there is a double type of structure of the uterus. The cat has uterus horn, double body containing the median septum that extends to the beginning of the general neck formation of. The wall of the uterus regardless of the department consists of three main shells: endometrium, myometrium and perimeter. In the same type of the uterus, such as rat and rabbit, it was detected at a histological level, differences in the structure of the cervix. For rats, cervix, unlike that of rabbits, by attaching the outer portion of the throat joint between two morphologically different histogenetic and epithelia, similar structure of the zone in the cervix cat. Myometrium of the uterus is not dependent on the type of the uterus, consists of three layers - the inner (submucosal) formed by cycle oriented myocytes; medium (vascular) with a small amount by coso oriented smooth muscle; outdoor (upper) cells coso direction. Plot merger medial wall is characterized by the union of the perimeter and the outer layer of the myometrium, with all representatives. Vascular layer plays an important role in the fusion of the medial caudal parts of the uterus walls. In the distal part of the cervix maximum development inner layer gets to form a circular sphincter.
