1: Describe the changes in the neuron membrane that occur throughout the course of an action potential. 2: Mention: Resting state, threshold, depolarization, repolarization, and hyperpolarization. 3: mention how the action potential is related to neuron communication.
Since you have asked multiple question, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question.
Neurons are the electrically conducting functional units of the nervous system. In neurons an action potential is said to occur when the membrane potential of a specific cell location rapidly rises and then drops leading to depolarization, which then causes adjacent cells/locations to depolarize. The initiation and propagation of an action potential is a multi-step sequential process which involves changes in the neuron membrane, described as follows.
