Question

Quizplus · Accepted Answer

The all-or-none principle is at play when the electrical threshold of the nerve cell membrane is reached, causing the propagation of the action potential. As the potential travels the length of the nerve, saltatory conduction occurs as the potential proceeds from one node of Ranvier to the next, all the way to its target organ or muscle.
