WebbSchwann cells (SCs) are a type of glial cell that surrounds neurons, keeping them alive and sometimes covering them with a myelin sheath, and are the major glial cell type in … WebbAll of these cells are found in the grey matter of the spinal cord. They are quite difficult to recognise in H&E sections, as you can see here, where only astrocytes can reliably be identified. Peripheral nervous system In the peripheral nervous system, there is one type of supporting cell, the Schwann cell.

They myelinate peripheral nerves and serve as the primary glial cells of the peripheral nervous system (PNS), insulating and providing nutrients to axons. Myelination increases conduction velocity along the axon, allowing for the saltatory conduction of impulses.
