stapedius muscle

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 human body.

Questions

Where is the stapedius muscle?

It sits in the head, within the muscular and sensory systems. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the stapedius muscle connect to?

Part of: middle ear.

Is the stapedius muscle the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
