General Information
Term smooth muscle contraction ID (Ontology) GO:0006939 (Gene Ontology)
Definition A process in which force is generated within smooth muscle tissue, resulting in a change in muscle geometry. 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. Smooth muscle differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length.[ ISBN:0198506732 ]
Also Known As "visceral muscle contraction"
