Question
Chapter 12.8, Problem 22WDL
Summary Introduction
To determine:
The significance of threshold membrane potential in the initial segment of a neuron.
Concept introduction:
The unequal distribution of positive and negative charge across the cell membrane results in membrane potential of a cell. When the membrane potential of an axon in a specific location rises and falls, it causes a series of electrical response or action potential. Action potential helps in the communication between cells.
