nerve sheath

Neural fiber casing

A nerve sheath is the protective covering that surrounds nerve fibers, insulating them and facilitating signal transmission.

The most familiar is the myelin sheath, a fatty layer that speeds electrical impulses along neurons.

Damage to nerve sheaths can cause neurological conditions: Multiple sclerosis attacks the myelin sheath.
