The myelin sheath is a protective layer that surrounds the axons of neurons, acting as an insulator to facilitate the rapid transmission of electrical signals along the nerve fibers. It is composed primarily of lipids and proteins, and its presence allows for saltatory conduction, where impulses jump between the nodes of Ranvier, increasing the speed of signal conduction. Additionally, the myelin sheath helps maintain the integrity of the axon and supports overall neuronal health.

What is the sheath of the Schwann Cell also called?
Surrounding the myelin sheath, there is a thin membrane called neurilemmal sheath. This is also called neurilemma or sheath of Schwann. This contains Schwann cells, which have flattened and elongated nuclei. The cytoplasm is thin and modified to form the thin sheath of neurilemma enclosing the myelin sheath. One nucleus is present in each internode of the axon. The nucleus is situated between myelin sheath adn neurilemma. At the node of Ranvier (where myelin sheath is absent), the neurilemma invaginates and runs up to axolemma in the form of a finger like process. In nonmyelinated nerve fiber, the neurilemma continuously surrounds axolemma. Neurilemma is absent in central nervous system. Neurilemma is necessary for the formation of myelin sheath (myelinogeneis).

No, the outermost sheath of a hair is the cuticle, which is a protective layer made up of overlapping cells. The connective tissue root sheath surrounds the hair follicle and is involved in providing structural support to the hair.
