| Schwann cell | A specialised glial cell that wraps around vertebrate axons providing extremely good electrical insulation. Separated by nodes of Ranvier about once every millimetre, at which the axon surface is exposed to the environment. See: saltatory conduction, myelin. (18 Nov 1997) |

| Schwann cell unit | A single Schwann cell and all of the axons lying in troughs indenting its surface; this unit regarded as an unmyelinated fibre in the peripheral nervous system. (05 Mar 2000) |
| schwann cells | Neuroglial cells of the peripheral nervous system which form the insulating myelin sheaths of peripheral axons. (12 Dec 1998) |
| schwann's white substance | <anatomy> The substance of the medullary sheath. Source: Websters Dictionary (01 Mar 1998) |
| Schwann, Theodor | <person> Taught Anatomy and Physiology in Berlin, became Professor of Anatomy in Louvain and was later Professor of Comparative Anatomy and Physiology at Liege. Was an early advocate (1838) of the cellular doctrine of tissues and the originator of the neuronal theory of the nervous system. Schwann cell - produces myelin in the peripheral nervous system. Mikroskopische Untersuchungen ueber die Uebereinstimmung in der Struktur und dem Wachstum der Thiere und Pflanzen. Berlin. 1839. Lived: 1810-1882. B. Neuss, Prussia, Dec 7th, 1810, d. Cologne, Jan 11th, 1882. (05 Dec 1998) |
| schwannoma | <tumour> A benign, encapsulated neoplasm in which the fundamental component is structurally identical to a syncytium of Schwann cells; the neoplastic cells proliferate within the endoneurium, and the perineurium forms the capsule. The neoplasm may originate from a peripheral or sympathetic nerve, or from various cranial nerves, particularly the eighth nerve; when the nerve is small, it is usually found (if at all) in the capsule of the neoplasm; if the nerve is large, the neurilemoma may develop within the sheath of the nerve, the fibres of which may then spread over the surface of the capsule as the neoplasm enlarges. Microscopically, neurilemoma's are composed of combinations of two cell types, Antoni types A and B (see below), either of which may be predominant in various examples of neurilemoma's. See: neurofibroma. Synonym: neurilemoma, neuroschwannoma. Origin: Theodor Schwann + -oma (05 Mar 2000) |
| schwannoma derived growth factor | <growth factor> A growth factor containing an EGF like domain, mitogenic for astrocytes, Schwann cells and fibroblasts. (18 Nov 1997) |
| schwannosis | A non-neoplastic proliferation of Schwann cells in the perivascular spaces of the spinal cord; seen particularly in older patients, especially those with diabetes mellitus. (05 Mar 2000) |
| sheath of Schwann | <anatomy> The delicate outer sheath of a nerve fibre; the primitive sheath. The perineurium. Origin: NL, from gr. Nerve + peel, skin. Source: Websters Dictionary (01 Mar 1998) |
