Question

Quizplus · Accepted Answer

Vertebrate skeletal muscles are categorized as excitable cells because their membranes generate and conduct action potentials. This is what allows them to contract in response to stimuli from the nervous system. A and E are incorrect because they describe general characteristics of muscle cells rather than specific aspects of excitable cells. C is incorrect because skeletal muscles do not secrete neurotransmitter. B is also incorrect because while electric charges can stimulate muscles, it is the action potential that is the defining characteristic of excitable cells.
