MeSH Heading: Otolithic Membrane
Tree Number(s): A09.246.300.909.625.125.680; A09.923.500.625.125.680
Unique ID: D010037
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D010037
Scope Note: A gelatinous membrane overlying the acoustic maculae of SACCULE AND UTRICLE. It contains minute crystalline particles (otoliths) of CALCIUM CARBONATE and protein on its outer surface. In response to head movement, the otoliths shift causing distortion of the vestibular hair cells which transduce nerve signals to the BRAIN for interpretation of equilibrium.
Entry Term(s): Otoconia; Otoliths; Statoconia
