[Human Scarpa ganglion cell sheath]. 1975

J Perre, and J M Sterkers, and M Ohresser, and J F Foncin

The ganglion vestibulare (Scarpa) has been studied with the electron microscope on thirteen operative specimens (neurectomy for Meniere's vertigo) and two random autopsy specimens. Neuroganglionar cell bodies are enclosed in a Schwann sheath, without any myelin. This observation is at variance with previous descriptions in various vertebrate forms.

UI MeSH Term Description Entries
D009186 Myelin Sheath The lipid-rich sheath surrounding AXONS in both the CENTRAL NERVOUS SYSTEMS and PERIPHERAL NERVOUS SYSTEM. The myelin sheath is an electrical insulator and allows faster and more energetically efficient conduction of impulses. The sheath is formed by the cell membranes of glial cells (SCHWANN CELLS in the peripheral and OLIGODENDROGLIA in the central nervous system). Deterioration of the sheath in DEMYELINATING DISEASES is a serious clinical problem. Myelin,Myelin Sheaths,Sheath, Myelin,Sheaths, Myelin

D014725 Vestibular Nerve The vestibular part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The vestibular nerve fibers arise from neurons of Scarpa's ganglion and project peripherally to vestibular hair cells and centrally to the VESTIBULAR NUCLEI of the BRAIN STEM. These fibers mediate the sense of balance and head position. Scarpa's Ganglion,Ganglion, Scarpa's,Nerve, Vestibular,Nerves, Vestibular,Scarpa Ganglion,Scarpas Ganglion,Vestibular Nerves
