During a relative refractory period:
A) an axon can transmit impulses comparable to a resting neuron.

E) neurons can only transmit several impulses per second.

Question

Quizplus · Accepted Answer

During the relative refractory period, the axon can transmit impulses, but it requires a higher threshold stimulus than normal because some sodium channels have returned to a resting state, but not all.
