General Information
Term relaxation of muscle ID (Ontology) GO:0090075 (Gene Ontology)
Definition A process in which the extent of muscle contraction is reduced. Muscle relaxation can involve a number of processes including the removal of calcium from the cytoplasm to the sarcoplasmic reticulum lumen through the action of Ca2+ ATPases. In some muscles, calcium-independent pathways also play a role in muscle relaxation by decreasing the phosphorylation state of myosin light chain.[ PubMed:19996365 ]
