C)a neural impulse that carries information along the axon of a neuron
D)the firing of a nerve, either toward or away from the brain

Question

Quizplus · Accepted Answer

An action potential is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane with a characteristic pattern. In neurons, this is the mechanism that allows them to transmit signals over long distances, specifically along the axon to communicate with other neurons or muscles. This process is fundamental to neural function, involving the movement of ions in and out of the neuron, which generates the electrical signal known as the action potential.
