Question

An afterpotential is:______
A. a brief depolarization that follows an action potential (overshoot).
B. a brief hyperpolarization that follows an action potential (undershoot).
C. the portion of an action potential between 0 and +30 mV.
D. a brief hyperpolarization that follows an EPSP (undershoot).

Answer 1

Answer:

Answer is B.  a brief hyperpolarization that follows an action potential [ undershoot ].

Explanation:

An after potential can also be explained or described  as a sequence of electrical charges following action potential .

In order word, an action potential can be described as a rapid electrical signal traveling along the axon.

It should be noted that after potential can be positive or negative. The positive afterpotential is known as hypopolarization, and it is a small positive membrane potential occurring during the recovery of an actionpotential by a muscle cell or neuron. The negative effect of this is described as the negative afterpotential , which is hyperpolarization.
