stapedius muscle in dogs

The muscle that stabilizes the stapes bone. The stapedius emerges from a pinpoint foramen in the apex of the pyramidal eminence (a hollow, cone-shaped prominence in the posterior wall of the tympanic cavity), and inserts into the neck of the stapes. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the stapedius muscle is

The muscle that stabilizes the stapes bone. The stapedius emerges from a pinpoint foramen in the apex of the pyramidal eminence (a hollow, cone-shaped prominence in the posterior wall of the tympanic cavity), and inserts into the neck of the stapes. [WP,unvetted]. The atlas records it as a muscle at the organ scale in the dog.
