It thus transpires that the prepuce and sheath, the epithelial surfaces of which face inwardly while the penis is at rest with a cavity be- tween them and the penis, become reversed when the organ is erected and constitute its immediate covering with its epi- thelium facing outward. The general plan is indicated in Figs. 8-11. B. The Female Generative Organs The genital system of the mammalian female consists of the ovaries, oviducts, uterus, cervix, vagina, and vulva. 1.
