Summary Introduction

To review:

The given blank space in the statement, “The myelinated segment of an axon that is covered by a glial cell is called a/a __; the gaps between glial cells where the axolemma is exposed are called____.”

Introduction:

An axon is responsible to conduct the action potential in the cell body. A myelin is the concentric layers of the plasma membrane which is wrapped around the body of the axon forming a sheath which is termed as the myelin sheath. The neurons of both the CNS (central nervous system) and the PNS (peripheral nervous system) are enclosed by the myelin sheath by neuroglial cells.
