Question

what is the ability of muscle cells to shorten called? multiple choice contractility excitability conductivity elasticity reactivity

Explanation:

Contractility is the property of muscle cells that allows them to shorten. Excitability refers to the ability to respond to stimuli, conductivity is related to the transmission of electrical impulses, elasticity is the ability to return to the original shape after being stretched, and reactivity is a general term for responding to a stimulus. Muscle - cell shortening is specifically called contractility.

Answer:

A. Contractility
