Detailed explanation-1: -A myelin sheath is a sleeve (sheath) that’s wrapped around each nerve cell (neurons). It’s a protective layer of fat (lipids) and protein that coats the main “body” section of a neuron called the axon.
Detailed explanation-2: -Myelin sheath is a substance which is found on neurons within the central nervous system (CNS) and the peripheral nervous system (PNS). Myelin sheath is the protective layer that wraps around the axons of neurons to aid in insulating the neurons, and to increase the number of electrical signals being transferred.
Detailed explanation-3: -Answer and Explanation: Dendrites may or may not be myelinated, depending upon their location. Most of the myelinated axons are found in the peripheral nervous system because the nerve impulses must travel over greater distances. In the central nervous system, short dendrites are present.
