smooth muscle contraction uterine smooth muscle contraction http://id.loc.gov/authorities/subjects/sh93004641 http://purl.obolibrary.org/obo/GO_0070471 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. contraction of the uterus contraction of uterus myometrial contraction myometrial smooth muscle contraction myometrium contraction uterine contraction uterine smooth muscle contractions
