Question

Quizplus · Accepted Answer

Axons have voltage-gated sodium (Na+) and potassium (K+) channels which allow for the depolarization and repolarization of the membrane potential during an action potential. Chemically gated channels refer to ligand-gated channels which are typically found in dendrites and cell bodies. Voltage-gated calcium (Ca2+) channels may also be present in axons, but they are not the primary channels involved in generating and propagating the action potential.
