- Sex hormones secreted by the ovary can stimulate uterine smooth muscle fibers and cause hypertrophy and proliferation corresponding to the sexual cycle. In addition, the smooth muscle fibers of the myometrium during pregnancy can be enlarged to the maximum value of mammalian smooth muscle (more than 500 microns). Uterine muscles can contract in response to oxytocin in the posterior pituitary hormone during delivery.
- The uterine muscle layer is thicker, 0.8cm in non-pregnancy, and consists of a large number of smooth muscle bundles and a small amount of elastic fibers. It is divided into an inner layer (circular arrangement of muscle fibers), a middle layer (cross arrangement of muscle fibers), and an outer layer (row of muscle fibers). Compression of blood vessels during uterine contraction can effectively control uterine bleeding.
