Schwann Cells

Meaning

Schwann Cells are the principal glial cells of the peripheral nervous system (PNS) that play a vital role in supporting and insulating peripheral nerve axons, primarily by forming the myelin sheath. This fatty, protective layer is essential for the rapid and efficient conduction of electrical impulses along the nerve fibers, which are critical for both motor and sensory function. Their health and function are closely linked to systemic metabolic and hormonal status, as demyelination can lead to peripheral neuropathies.
