Contracting muscles produce heat as a byproduct, and this contributes to the maintenance of normal body temperature. The contraction and relaxation of muscles produce movement at various joints around the body. Elasticity refers to the ability of a muscle to recover its original shape after contraction or extension. Extensible refers to the ability of a muscle to stretch Contractility refers to the ability of a muscle to shorten in response to an action potential.
