Detailed explanation-1: -Schwann cell, also called neurilemma cell, any of the cells in the peripheral nervous system that produce the myelin sheath around neuronal axons. Schwann cells are named after German physiologist Theodor Schwann, who discovered them in the 19th century.

Detailed explanation-2: -The vast majority of tumors of the peripheral nervous system arise from the cells of Schwann, rather than from the nerve cells themselves. Schwann cells, or neurilemma, are cells that are responsible for the production of the myelin sheath around neuronal axons.

Detailed explanation-3: -Schwann cells, also called neurolemmocytes, have two structural types. They may form a thick myelin sheath, or an indented plasma membrane that folds around peripheral axons in the PNS. Where a Schwann cell covers an axon, the outer cell surface is called the neurilemma.

Detailed explanation-4: -Neurilemma (also known as neurolemma, sheath of Schwann, or Schwann’s sheath) is the outermost nucleated cytoplasmic layer of Schwann cells (also called neurilemmocytes) that surrounds the axon of the neuron. It forms the outermost layer of the nerve fiber in the peripheral nervous system.

Detailed explanation-5: -Schwann cells (SCs) are a type of glial cell that surrounds neurons, keeping them alive and sometimes covering them with a myelin sheath, and are the major glial cell type in the peripheral nervous system. They play essential roles in the development, maintenance, function, and regeneration of peripheral nerves.
