MSH: Contraction of the UTERINE MUSCLE.,GO: A process in which force is generated within smooth muscle tissue, resulting in a change in muscle geometry. This process occurs in the uterus. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. The uterus is a muscular organ of the female mammal for containing and usually for nourishing the young during development prior to birth. [GOC:sl],NCI: A tightening of the involuntary smooth muscles of the uterus.
