Question

Which of the following is the most common location where action potentials originate?

A. Dendrites

B. cell body

C. axon hillock

D. synaptic cleft

E. synaptic bouton

Answer 1

The most common location where action potentials originate is the axon hillock.

Step-by-step explanation:

The most common location where action potentials originate is the axon hillock. The axon hillock is the region of the neuron where the signals from the dendrites are integrated and where the decision to generate an action potential is made. This region has a high concentration of voltage-gated sodium channels which are responsible for initiating and propagating the action potential.
