Question

Action potentials occur in the membrane of

A) dendrites.
B) cell bodies.
C) axons.
D) A and C
E) B and C

Answer 1

Action potentials occur in the membrane of both dendrites and axons.

Step-by-step explanation:

The correct answer is D) A and C. Action potentials occur in the membrane of both dendrites and axons.

Action potentials are brief, rapid changes in the membrane potential of a neuron that allow for the transmission of signals. They occur when there is a sudden increase in the permeability of the neuronal membrane to sodium ions (Na+), which causes a rapid depolarization. This depolarization then triggers a cascade of events that propagate the action potential down the axon towards the synapse.
