AP PSYCHOLOGY

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 consists of lipids and proteins which make up a fatty substance and is white in appearance. This forms the protective sleeve that wraps around the axon of neurons. The sheath is made up of many concentric layers of plasma membrane, wrapped tightly around the axon.

Detailed explanation-3: -The axon is covered by a myelin sheath. The axon passes information to the next neuron or other cell in the body. A myelin sheath. The axons have a protective covering called myelin.

Detailed explanation-4: -Schwann cells surrounds the axons to form the myelin sheath. The myelin sheath provides support to neurons by accelerating impulses. It also acts as an effective electrical insulator and provides protection to the neurons from external shock.

Detailed explanation-5: -In most neurons, the axon is surrounded by a white insulating sheath called myelin or medullary. The outermost thin sheath covering of the axon is called neurilemma.
