The number of action potentials occurring per unit of time is referred to as the:
A) sodium-potassium pumping rate
B) propagation of action potentials.
C) firing rate.
D) action potential magnitude.

Question

Quizplus · Accepted Answer

The firing rate refers to the number of action potentials that occur per unit of time. This can be measured in neurons and can vary based on different factors, including external stimuli and neuronal activity. Option A refers to the rate at which the sodium-potassium pump operates, which is not related to the firing rate. Option B refers to how action potentials propagate along the axon of a neuron, but not the frequency at which they occur. Option D refers to the amplitude or strength of an individual action potential, but not the frequency at which they occur.
