The Tissues of Adult Female Reproductive System of the Pipistrellus Kuhlii Bat: Comparative Study with other Mammals

This study is attempt for investigating the tissues, which comprise the female reproductive system of the bat. Then, compare it with the same system of other mammals. The bat has been anatomized and the organs of female reproductive  system was taken away. They include: ovary, ovarian duct and uterus, where they have been studied histological.

The results of the microscopic investigation of the tissue of the female bat, showed that  the ovary has two parts; an outer  cortex  and  an inner medulla. The cortex consists of  follicles, different  growth stages and the proper tissues have net of connective tissue fibers.  The medulla, consists of loose elastic fiber connective tissues and numerous blood vessels and nerves. The ovarian duct consist of a mucosa layer, which consists of simple columnar epithelial tissue with secretory cells. Also, a muscular layer underlines the  mucosa layer. It regulates the internal circulatory layer and external thinner layer. Serosa lining of the duct with layer of peritoneum that consists of loose connective tissue lining the surface with mesothelium. Lastly the uterus has bicornuate uterus that is the same as other mammals like sheep, whales, insectivorous and large bats. The uterus is  the thickest part of the of female reproductive system of the bat. The uterus consists of outer layer or perimetrium as the serosa, the middle layer or myometrium is the muscularis and the endometrium as the mucosa.
