Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
This insulating material forms a layer, around the axon of a neuron. It enables electrical signals to travel down the axon at higher speeds.
A
neuron
B
myelin sheath
C
dendrite
D
neurotransmitter
Explanation: 

Detailed explanation-1: -Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells.

Detailed explanation-2: -The myelin sheath is a layer of fatty tissue surrounding the axon of a neuron that both acts as an insulator and allows faster transmission of the electrical signal.

Detailed explanation-3: -An axon is insulated by a myelin sheath throughout its length to increase the velocity of these electrical signals allowing signals to propagate quickly. Axons which are covered by a myelin sheath, a multilayer of proteins and lipids, are said to be myelinated.

Detailed explanation-4: -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.
