SCHWANN CELL Meaning and
Definition
-
A Schwann cell refers to a type of glial cell found in the peripheral nervous system (PNS) which is responsible for promoting regeneration and providing support to neurons. Named after German physiologist Theodor Schwann who first described them, Schwann cells play a vital role in ensuring the proper functioning of the PNS.
The main function of Schwann cells is to produce a myelin sheath around nerve fibers in the PNS. This myelin sheath is an insulating layer that wraps around the nerve fibers, allowing for faster and more efficient transmission of nerve impulses. The presence of myelin is critical in enhancing signal conduction and protecting nerve fibers from damage, as the myelin sheath prevents electrical signals from leaking out of the nerve fibers.
In addition to producing myelin, Schwann cells also play a crucial role in nerve regeneration. After injury or damage to a nerve, Schwann cells form a pathway called the Bands of Büngner, which guides and supports the regrowth of damaged nerve fibers. This process is essential for the restoration of sensory and motor functions in the PNS.
Overall, Schwann cells are instrumental in maintaining the integrity and functionality of the peripheral nervous system. Their production of myelin and facilitation of nerve fiber regeneration ensures efficient transmission of electrical signals and aids in the recovery and repair of damaged nerves.

Etymology of SCHWANN CELL
The word "Schwann cell" is named after its discoverer, Theodor Schwann, a German physiologist and anatomist. Schwann cells were first described by Schwann in the 19th century as the principal cellular component of the peripheral nervous system responsible for producing the insulating myelin sheath around neurons. As a tribute to his contribution to the field of neurobiology, these cells came to be known as Schwann cells.
