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:0030157 term browser browse the term
Definition:any structural anomaly of the tiny striated muscle found in the pyramidal eminence on the posterior wall of the tympanic cavity, whose tendon inserts onto the neck of the stapes; like the tensor tympani, it helps to dampen loud sounds; it is innervated by a small branch from the facial nerve
Synonyms:exact_synonym: abnormal stapedius morphology
