The characteristic ability of neurons to respond to a stimulus and convert it into a nerve impulse is called
A)depolarization
B)hyperpolarization
C)electrical excitability
D)threshold
E)contractility

Question

Quizplus · Accepted Answer

Electrical excitability is the characteristic ability of neurons to respond to a stimulus and convert it into a nerve impulse. Depolarization and hyperpolarization refer to specific changes in membrane potential that occur during this process. Threshold refers to the minimum level of stimulation required to initiate a nerve impulse. Contractility is a characteristic of muscle cells, not neurons.
