The processes influencing the shift in threshold potential which initiates an action potential most commonly involve (1) ; the processes leading to the propagation of an action potential along an axon involve (2)

Question

Quizplus · Accepted Answer

The initiation of an action potential involves chemically gated ion channels, which respond to neurotransmitters and cause depolarization to reach the threshold. The propagation of an action potential along an axon involves voltage gated ion channels, which open in response to changes in membrane potential, allowing the action potential to travel down the axon.
