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.

Accession:MP:0030154 term browser browse the term
Definition:any structural anomaly of the small, air-filled, mucosa-lined cavity that is located in the petrous portion of the temporal bone and houses the auditory ossicles and intratympanic muscles (tensor tympani and stapedius) as well as the chorda tympani and the tympanic plexus of nerves; it is split into two parts: the tympanic cavity proper (the space directly internal to the tympanic membrane) and the epitympanic recess or attic (the space superior to the tympanic membrane)
Synonyms:exact_synonym: abnormal middle ear cavity morphology
