MAMMALIAN PHENOTYPE - ANNOTATIONS

The Mouse Adult Gross Anatomy Ontology and Mammalian Phenotype Ontology are downloaded weekly from the Mouse Genome Informatics databases at Jackson Laboratories (ftp://ftp.informatics.jax.org/pub/reports/index.html). For more information about these ontologies, see the MGI Publications Page at http://www.informatics.jax.org/mgihome/other/publications.shtml.

Term:abnormal inner hair cell stereociliary bundle morphology

Accession:MP:0004532 term browser browse the term
Definition:any structural anomaly or disruption of the typically linear or U-shaped pattern of arrangement of mechanosensitive hair bundles located at the apical end of cochlear IHCs; each hair bundle is normally composed of ~100 nonmotile, actin-filled microvilli (stereocilia) arranged in rows of increasing height and coupled to one another by morphologically distinct links: tip links, horizontal top connectors, shaft connectors, and ankle links; most hair bundles also possess a single motile kinocilium immediately adjacent to the tallest row of stereocilia; a fifth link type, the kinocilial link, connects the kinocilium to its neighboring stereocilia
Synonyms:exact_synonym: abnormal IHC bundles;   abnormal IHC stereocilia;   abnormal IHC stereociliary bundles
