Question
Chapter 27, Problem 1BYB
Summary Introduction
To describe:
The function of myelin.
Given:
The axons of the neurons may have a protective covering made up of lipid materials called as myelin.
Introduction:
Based on myelin the nerve cell may be divided into two categories i.e., myelinated and non-myelinated neurons. The myelin has a variety of functions.
Expert Solution & Answer
Explanation of Solution
The main functions of the myelin sheath are shown in the below diagram.
Conclusion
Thus, the presence of myelin sheath insulates, prevents the flow of ions and increases the velocity of conduction of action potential along the axon.
