Document Summary
The vagina serves as the birth canal through which the baby is delivered. Its mucosa contains stratified squamous epithelium to provide resistance against abrasion. The fornix is the upper region around the cervix. The vaginal muscularis is composed of smooth muscle. The external genitalia include the mons pubis, labia majora (singular = labium majus), labia minora (singular = labium minus), and clitoris. The mons pubis is the fatty area over pubic symphysis. The labia are homologous with the male scrotum. The vestibule is the open area between the labia minora. The clitoris is composed of erectile tissue called the corpora cavernosa, which become engorged with blood during sexual activity. The hymen is a flap of mucous membrane partially covering vaginal orifice. The greater vestibular glands are homologous with the bulbourethral glands of the male. They secrete mucus to help lubricate the area during intercourse. The mammary glands are modified sweat glands that produce and release milk.
