MP:0003149 | abnormal tectorial membrane morphology | "malformation, malfunction or absence of the overlaying membrane of cochlear duct, an extracellular matrix of the inner ear that contacts the stereocilia bundles of specialized sensory hair cells; sound induces movement of these hair cells relative to the tectorial membrane, deflects the stereocilia, and leads to fluctuations in hair cell membrane potential, transducing sound into electrical signals" [anna:Anna Anagnostopoulos, Mouse Genome Informatics Curator, J:77634] |
