Chapter 16, Problem 2CP
Summary Introduction
To determine:
The number of motor neurons need to carry the action potential from the spinal cord to smooth muscles in the wall of intestine.
Concept introduction:
Action potential is an electrical impulse that is needed to transfer the message from CNS to the organs muscles that carries out response to the stimulus. The source of energy for the development of the action potential is derived from the sodium and potassium ions. It is simply a concept of changes in the ionic concentration. It is produced by a type of passage or gate known as the voltage gated ion channels in the cell membrane.
