In contrast to the cervix, the uterine substance (myometrium) is 85% smooth muscle and only 15% connective tissue. Except for the anteroinferior portion of the corpus, which is invested by the bladder, the uterus is covered by peritoneum. The adult nonpregnant uterus weighs about 90 g and is about 7–8 cm long and about 4 cm in its widest diameter. However, considerably larger sizes and increased weight occur with hormonal stimulation and after childbirth. During pregnancy, the uterus, which increases to weigh about 1000 g, literally balloons to accommodate the gestation.

The blood supply is from the vaginal artery (a descending branch of the uterine artery) and from the middle hemorrhoidal and internal pudendal arteries. It is drained by the pudendal, external hemorrhoidal, and uterine veins. FIGURE 2-4.
