tensor tympani muscle

In some people with hyperacusis, the tensor tympani muscle can contract just by thinking about a loud sound.

The tensor tympani muscle and the stapedius muscle suddenly contract.

It is attached to the tensor tympani muscle, which constantly pulls it inward.

Some individuals can voluntarily produce this rumbling sound by contracting the tensor tympani muscle of the middle ear.

Compare also the role of the tensor tympani muscle, which primarily dampens those sounds associated with chewing.

They include the Stapedius muscle and Tensor tympani muscle.

When presented with a high-intensity sound stimulus, the stapedius and tensor tympani muscles of the ossicles contract.

In many people with hyperacusis, an increased activity develops in the tensor tympani muscle in the middle ear as part of the startle response to some sounds.

On entering the cranium it runs in the canal for the tensor tympani muscle and supplies this muscle and the lining membrane of the canal.

For example, the muscles of the middle ear (e.g. the tensor tympani muscle) in many mammals contract reflexively in reaction to loud sounds which may injure the hearing ability of the organism.

There, he was the first to demonstrate physiologically that the innervation of the tensor tympani muscle was by the trigeminal nerve and that the innervation of the stapedial muscle was by the facial nerve.

Tympanic membrane displacement (TMD) technique, proposed nearly twenty years ago by Marchbanks exploits the effect of intracranial pressure on the acoustic reflex, i.e. a reflex contraction of the stapedius and tensor tympani muscles in response to a sound.

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.

Following exposure to intolerable sounds, this contraction of the tensor tympani muscle tightens the ear drum, which can lead to the symptoms of ear pain/a fluttering sensation/a sensation of fullness in the ear (in the absence of any middle or inner ear pathology).

The stapedius stiffens the ossicular chain by pulling the stapes (stirrup) of the middle ear away from the oval window of the cochlea and the tensor tympani muscle stiffens the ossicular chain by loading the eardrum when it pulls the malleus (hammer) in toward the middle ear.

It is situated on the anterior (frontal) surface of the petrous portion of the temporal bone close to its angle of junction with the squama temporalis; it is prolonged backward so as to roof in the tympanic antrum, and forward to cover in the semicanal for the tensor tympani muscle.
