    J^ ^4 the fetus. The hymen is a fold of the vaginal mucosa guarding its lower orifice, the introitiis vagincs. The Vulva.—The external genitals, or vulva (Fig. 5], comprise the labia majora and minora, the clitoris, the vesti- bule, the fossa navicularis, and the mons veneris. The labia majora, the ana- logue of the scrotum in the male, consist of two thick folds \ of integument extending for about 7^ cm. (3.0018 in.) from the symphysis pubis above to their junction below—\}:iQposte- rior commissure, or fourchet— about 2^ cm. (i in.) in front of the anus. In structure they are composed of adipose tissue, blood-vessels, and nerves, with an internal mucous and an exter- nal cutaneous surface, the latter being clothed with short, crisp hairs. Bartholiid's glands, or the glands of Duverney or of Hu- guier, one on either side, are imbedded in the lower third of the labia majora. The rima pudenda?, the fissure separating the labia. The fourchet is torn in the majority of labors occurring in primiparae. The labia ndnora, or nymphce, are two small mucous folds situated within the greater lips, and uniting above to form the prepuce of the clitoris. They extend downward to about the middle of the labia majora, where they merge into the latter. A large number of sebaceous glands are found on their surfaces.
