Definitions related to muscle contraction:
-
A process in which force is generated within 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.Gene Ontology DictionaryGene Ontology Consortium, 2021
-
A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
Process leading to shortening and/or development of tension in muscle tissue; occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.CRISP ThesaurusNational Institutes of Health, 2006
-
The process where thick (myosin) and thin (actin) filaments slide against each other to produce a shortening or tensing of the muscle cell or fiber.NCI ThesaurusU.S. National Cancer Institute, 2021
