The myometrium
The medical term for a hormone that stimulates contraction of the uterus during labor is oxytocin.
The uterus is a muscle. During menses it contracts to expel the uterine lining and menstrual blood. This is a mild from of the contraction it does to push out a baby. The contraction can press against a blood vessel and cut off the blood supply.
