stapedius muscle

The tensor tympani muscle and the stapedius muscle suddenly contract.

(Compare to the more general dampening function of the stapedius muscle.)

If the injury is distal to the stapedius muscle, the reflex is still functional.

They include the Stapedius muscle and Tensor tympani muscle.

Like the stapes bone to which it attaches, the stapedius muscle shares evolutionary history with other vertebrate structures.

The stapes is also stabilized by the stapedius muscle, which is innervated by the facial nerve.

As the stapedius muscle is innervated by the facial nerve, a measurement of the reflex can be used to locate the injury on the nerve.

Your Answer: Correct Answer: The stapedius muscle is the smallest skeletal muscle in the body.

The stapedius muscle dampens the ability of the stapes vibration and protects the inner ear from high noise levels, primarily the volume of your own voice.

It also innervates the posterior belly of the digastric muscle, the stylohyoid muscle, and the stapedius muscle of the middle ear.

In human anatomy, the stapedial branch of posterior auricular artery, or stapedial artery for short, is a small artery supplying the stapedius muscle in the inner ear.

Before the nerve exits the skull via the stylomastoid foramen and after the nerve to the stapedius muscle has branched off, the facial nerve gives off the chorda tympani nerve.

Subjects were not properly rested for days in advance, or were exposed to loud noise in travelling to the tests which tensed the tensor timpani and stapedius muscles controlling low-frequency mechanical coupling.

Also, a small muscle (which is also seen in geckos) next to or upon the stapes, the stapedius, probably functions in the same way as the mammalian stapedius muscle does, damping strong vibrations.

The test measures the reflexive contraction of the stapedius muscle, which is important in protecting the ear from loud noises, such as a person's own speech which may be 90 dBSPL at the eardrum.

The cavity in the pyramidal eminence is prolonged downward and backward in front of the facial canal, and communicates with it by a minute aperture which transmits a twig from the facial nerve to the Stapedius muscle.

This could lead to hyperacusia (dysfunction of the stapedius muscle, innervated by CN VII) and vertigo (wrong interpretation from the vestibular semi-circular canal's endolymph acceleration caused by alteration of CN VIII).

To avoid deafening themselves, whenever a bat makes an echolocation emission, a small muscle in the bat's middle ear (the stapedius muscle) clamps down on small bones called ossicles, which normally amplify sounds between the ear drum and the cochlea.

The stapedius muscle, the smallest skeletal muscle in the body, connects to the stapes and is controlled by the facial nerve; the tensor tympani muscle connects to the base of the malleus and is under the control of the trigeminal nerve.
