Definition & Meaning of "schwann cell"

What is a "schwann cell"?

A Schwann cell, also known as a neurilemma cell, is a vital component of the peripheral nervous system. It is a specialized type of glial cell responsible for the production and maintenance of myelin sheaths. These cells play a crucial role in insulating and protecting nerve fibers, ensuring the efficient and rapid transmission of electrical impulses along the axons. In addition to their myelination function, Schwann cells also participate in nerve regeneration processes, contributing to the repair and recovery of damaged nerves. Through their intricate cellular processes and interactions, Schwann cells are essential for the proper functioning and integrity of the peripheral nervous system.
