Chapter 24, Problem 4WIO

Summary Introduction

To determine:

The event on artificially stimulating an axon so that the threshold potential is reached midway along its length.

Introduction:

A short reversal in the membrane potential that propagates like a wave along the membrane of the axon is known as the action potential. It will arise only if a cell’s threshold potential is reached. Once the action potential begins, additional Na⁺ flows into the cell using the sodium channels and the membrane get a positive charge on the inside.
