MSH: That phase of a muscle twitch during which a muscle returns to a resting position.,CSP: lessening of muscle tension.,GO: 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. [GOC:rl, PMID:19996365]
