Schwann Cells

Schwann cells are specialized glial cells in the peripheral nervous system that support and protect nerve fibers. They wrap around axons (the long projections of nerve cells) to form a myelin sheath, which acts like insulation. This myelin speeds up the transmission of electrical signals along the nerve, making communication within the nervous system more efficient. Additionally, Schwann cells help repair damaged nerves by supporting regeneration. They are essential for proper nerve function and communication between the brain, spinal cord, and the rest of the body.
