=The broad ligaments= are in reality one continuous structure formed by a fold of the peritoneum, which drops down over the uterus, investing the fundus, body, part of the cervix, and part of the posterior wall of the vagina. It unites on each side of the uterus to form a broad, flat membrane which extends laterally to the pelvic wall, dividing the pelvic basin into an anterior and posterior compartment, containing respectively the bladder and rectum. Between the folds of the broad ligament are situated the ovaries and ovarian ligaments, the Fallopian tubes, the round ligaments and a certain amount of muscle and connective tissue, blood vessels, lymphatics and nerves. =The round ligaments=, one on each side, are narrow, flat bands of connective tissue derived from the peritoneum and muscle prolonged from the uterus, and containing blood and lymph vessels and nerves. They pass upward and forward from their uterine origin just below and in front of the tubal entrance, finally merging in the mons veneris and labia majora. =The utero-sacral ligaments=, of which there is one on each side, arise in the uterus and, extending backward, serve to connect the cervix and vagina with the sacrum. =The utero-vesical ligaments=, one on each side, extend forward and connect the uterus and bladder. =The ovarian ligaments=, as previously described, are attached to the uterine wall and to the inner end of the ovary, one on each side. =The anterior ligament= is a portion of the peritoneum which dips down between the bladder and uterus, forming a pouch. It is known also as the uterine-vesical pouch, or the vesico-uterine excavation. =The posterior ligament= is formed in much the same manner by a portion of the peritoneum dipping down behind the uterus, in front of the rectum, and forming the recto-vaginal pouch. This is the Douglas’ cul-de-sac previously referred to. =External Genitalia.—The vulva=, or external genitalia, are situated in the _pudendal crease_ which lies between the thighs at their junction with the torso, and extends posteriorly from the pubis to a point well up on the sacrum. (Fig. 13.) =The mons veneris= is a firm cushion of fat and connective tissue, just over the symphysis pubis. It is covered with skin which contains many sebaceous glands and after puberty is abundantly covered with hair. [Illustration: FIG. 13.—Diagram of external female genitalia. (Redrawn from Dickinson.) ] =The labia majora= are heavy ridges of fat and connective tissue, prolonged from the mons veneris and extended down and back almost to the rectum, on each side, forming the lateral boundaries of the groove. They are lined with mucous membrane and covered with skin and hair, the latter growing thinner toward the perineum until it finally disappears.
