The ability of muscle cells to respond to nerve stimuli is called:
A) irritability.
B) contractility.
C) extensibility.
D) elasticity.

Question

Quizplus · Accepted Answer

Irritability is the ability of muscle cells to respond to nerve stimuli. This response includes the generation of an action potential and subsequent contraction of the muscle fiber. Contractility refers to the ability to actively generate tension and shorten, while extensibility and elasticity refer to the ability to stretch and return to the original length, respectively.
