Question
Chapter 26.3, Problem 6MC
Summary Introduction
To determine:
How do action potential indicate stimulus intensity and type.
Concept introduction:
Action potential is defined as the pulse-like wave of voltage gradient that passes axon and influences other neurons. It is a type of electrical potential that transmits signals to different parts of the body.
