NEET PG DENTAL EXAM

Detailed explanation-1: -Schwann cells are derived from the neural crest and play crucial roles in the maintenance and regeneration of the motor and sensory neurons of the peripheral nervous system (PNS). They are mainly required for insulating (myelinating) and supplying nutrients to individual nerve fibers (axons) of the PNS neurons.

Detailed explanation-2: -Myelin is made by oligodendrocytes in your brain and spinal cord (your central nervous system [CNS]) and by Schwann cells in your peripheral nervous system.

Detailed explanation-3: -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.
