Question

After initiating an action potential, there is a period of time called ______ during which a cell cannot generate another AP, no matter how strong the stimulus.
a. Relative refractory period
b. Absolute refractory period
c. Summate refractory period

Answer 1

Answer:

B. Absolute refractory period

Explanation:

Action potential has a refractory period that divides in two: relative and absolute. Relative refractory period allows the generation of another AP but needs a greater initial despolarization to reach the excitation threshold. Absolute refractory period cannot generate another action potential no matter how strong the stimulus is.
