A type of glial cell of the peripheral nervous system that helps separate and insulate nerve cells.

Neuroglial cells of the peripheral nervous system which form the insulating myelin sheaths of peripheral axons.

A supporting cell of the peripheral nervous system that aids the growth, development, function, maintenance and repair of peripheral nerves. Myelinating Schwann cells form the myelin sheath around large diameter axons while non-myelinating Schwann cells bundle together portions of several unmyelinated smaller diameter axons and may also play a role in the formation and maintenance of synaptic connections in the neuromuscular junction.

Schwann cell, any of the cells in the peripheral nervous system that produce the myelin sheath around neuronal axons. Schwann cells are named after German physiologist Theodor Schwann, who discovered them in the 19th century. These cells are equivalent to a type of neuroglia called...
