The whole thing! Labor is a series of contractions that cause the upper part of the uterus (fundus) to tighten and thicken which works to push the baby down and out - while the cervix and lower portion of the uterus stretch and relax, giving the baby a passage from inside the uterus and into the birth canal for delivery.

Muscular layer
Uterine muscle cells help make up the myometrium, which is the inner layer of the uterine wall. These muscle cells aid in inducing uterine contractions. They support stromal and vascular tissue as well.

Uterine myomas are also known as uterine fibroids. These fibroids grow from the smooth muscle layer of the uterus. This smooth muscle wall is known as the myometrium. The fibroids are most commonly benign (non-cancerous) tumors that are typically found during a woman's child-bearing years.
the serosa
The lining of the uterine cavity is called the "endometrium." It consists of the functional endometrium and the basal endometrium. Shedding of the functional endometrial lining in humans is responsible for menstrual bleeding

The wall of the uterus is made up of three main layers. The inner most layer is the Endometrium. The middle layer is the Myometrium and the outer most layer is the Perimetrium, or adventitia or serosa.
