The membrane potential at which an action potential is triggered is known as the
A) resting potential.
B) threshold.
C) absolute refractory period.
D) relative refractory period.

Question

Quizplus · Accepted Answer

The threshold is the membrane potential at which an action potential is triggered. The resting potential is the membrane potential when a neuron is not transmitting signals. The absolute refractory period is the time period where a neuron is incapable of generating another action potential. The relative refractory period is the time period where a neuron has a higher threshold for generating action potentials.
