Schwann cells

(shwahn),
cells of ectodermal (neural crest) origin that compose a continuous envelope around each nerve fiber of peripheral nerves; such cells are comparable with the oligodendroglia cells of brain and spinal cord; like the latter, they may form membranous expansions that wind around axons and thus form the axon's myelin sheath.

Schwann cells

(shwahn selz)
Cells of ectodermal (neural crest) origin that compose a continuous envelope around each nerve fiber of peripheral nerves.
Synonym(s): neurilemma cells, neurolemma cells.

Schwann,

Theodor, German histologist and physiologist, 1810-1882.
Schwann cell unit - a single Schwann cell and all of the axons lying in troughs indenting its surface.
Schwann cells - cells of ectodermal (neural crest) origin that compose a continuous envelope around each nerve fiber of peripheral nerves. Synonym(s): neurilemma cells
Schwann tumor
Schwann white substance - the lipid material present in the myelin sheath of nerve fibers; the medulla of bones and other organs.
schwannoma - Synonym(s): neurilemoma; neuroschwannoma
sheath of Schwann - a cell that enfolds one or more axons of the peripheral nervous system. Synonym(s): neurilemma
