Definitions:

Demyelinates

Demyelination refers to the process by which the myelin sheath, a protective covering of the nerve fibers in the brain and spinal cord, is damaged or destroyed, affecting the conduction of nerve impulses.

Somatic Motor Neurons

Neurons that transmit impulses from the central nervous system to skeletal muscles, facilitating voluntary muscle movements.

Schwann Cells

Specialized cells in the peripheral nervous system that wrap around nerve fibers, providing electrical insulation and helping in the regeneration of damaged nerves.

Oligodendrocytes

Glial cells in the central nervous system that produce myelin, the insulating layer around neurons.
