Question

Quizplus · Accepted Answer

Extensibility is the property of muscle that allows it to be stretched without causing damage. This is what allows Larry to stretch his leg muscles before going for a run without hurting himself. Contractility is the ability of muscle to contract, or shorten, to produce movement. Elasticity is the ability of muscle to return to its original shape after being stretched. Electrical excitability is the ability of muscle to respond to electrical signals and produce a contraction. While all of these properties are important for muscle function, only extensibility is directly relevant to Larry's stretching routine.
