Question
Chapter 12.9, Problem 28WDYL
Summary Introduction
To explain:
How frequency of action potential differs from the velocity of action potential propagation.
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.
