DictionarySeeSchwann cellSchwann cells
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. Synonym(s): neurilemma cells, neurolemma cellsSchwann 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.
