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.

The exertion of the power, possessed by muscles, of shortening themselves, or of contracting to produce motion: - muscular motion being the change in the situation and relation of organs, induced by muscular contraction. When a muscle contracts, its fibres assume more the zigzag direction, and the extremities approximate; but the bulk of the whole muscle is not augmented. This contraction takes place, at times, with extres velocity: a single thrill, in the letter R, can be pronounced in the 1-30,000th part of a minute. The force of contraction, Myodynamis, depends upon the healthy physical conditition of the muscle, combined with due energy of the brain. The duration, in voluntary motion, is for a certain time dependent upon the will: - contractions, excited involuntarily, cannot be so long maintained.

It has extensive homology can heterodimerize EGF EPIDERMAL GROWTH FACTOR), 3 receptor (RECEPTOR, 3) and the 4 receptor.
