Primary Functions

The fundamental or core roles that an organism, system, or component is naturally designed to perform.

Schwann Cells

Glial cells in the peripheral nervous system that wrap around axons, providing insulation (myelin) and support for nerve conduction.

Nerve Damage

Nerve damage involves harm or injury to nerve cells or fibers, leading to loss of function, pain, or numbness in the affected area of the body.

Neuron
