How is a nerve impulse generated when most sensory receptors are activated?
A)The action potential is converted to a binary code.
B)The membrane becomes hyperpolarized.
C)The membrane becomes repolarized.
D)The membrane becomes depolarized.

Question

Quizplus · Accepted Answer

When most sensory receptors are activated, the membrane potential of the neuron becomes less negative, which is known as depolarization. This depolarization can eventually reach the threshold potential, triggering an action potential which propagates down the axon to transmit the nerve impulse.
