Continuous or sporadic contraction of skeletal muscles around the body helps us to maintain our posture and position Elasticity refers to the ability of a muscle to recover its original shape after contraction or extension. The contraction and relaxation of muscles produce movement at various joints around the body. Electrical excitability refers to the ability of a muscle to respond to stimuli, such as neurotransmitters, by eliciting an electrical signal called an action potential. Contracting muscles produce heat as a byproduct, and this contributes to the maintenance of normal body temperature. Extensible refers to the ability of a muscle to stretch
