Matching Pairs properties of muscle tissueOnline version muscular system by Alexandria Moore 1 Contractile 2 Maintain body positions 3 Electrical excitability 4 Thermogenesis 5 Extensible 6 Body movements 7 Elastic 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. Contractility refers to the ability of a muscle to shorten in response to an action potential. 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 Continuous or sporadic contraction of skeletal muscles around the body helps us to maintain our posture and position Contracting muscles produce heat as a byproduct, and this contributes to the maintenance of normal body temperature.
