Morphological and histological study of uterus in domestic Iraqi sheep

الملخص EN

Present study were carried out on twenty adult local sheep.

The results were showed that the uterus of adult sheep are bicornate, it consist of equivalent and convex uterine horns attached with relatively long uterine body, horns coiled ventrally on themselves.

the statistical analysis results revealed a significant differences at (P0.05) between each of the length and diameter of the left and right horns and body, the right horn was significantly (p< 0.05) longer (5.7±0.6) than the left horn (5.03±0.85).

Respectively the diameter of the right uterine horn (0.71±0.180) was wider(P>0.05) than the diameter of the left uterine horn (.61±0.075).

The length of the uterine body was (2.62 0.3) with a diameter of 1.410.25.

The uterine wall of body and horns of an adult sheep is formed by three layers: the inner endometrium (mucosa ), middle myometrium, and the outer layer is perimetrium (serosa).

The epithelium of the endometrium may stratified or pseudostratified.

Simple, branched uterine (endometrial) glands extend into the lamina propria, interglandular lamina propria and basal lamina.

The myometrium is divisible into a thick, inner circular layer and a thin, outer longitudinal layer.

A richly vascularized (inter vascular connective tissue) and coiled artery usually separates the muscle layers.

The histochemical stains (PAS &Masson) gave negative results to uterus tissue.
