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.

Definition:any structural anomaly in the nonsensory epithelial cells located above the vestibular melanocytes and adjacent to the sensory structures in the utricle and in the ampullae at the ends of each of the semicircular canals; these cells provide and maintain the high potassium ionic environment within the vestibular labyrinth and are therefore homologous to the marginal cells of the stria vascularis; they are joined to each other by tight junctions and provide a barrier between endolymph and perilymph
