Vestigial human ear muscles react to sounds even if the external ear does not move. This could be used to build better earing aids. If you hear something interesting, you might prick up your ears.

Other possible symptoms of a TMD include: These muscles help to transmit vibrations from the eardrum and bones in the middle ear into the inner ear. What exactly causes MEM is unknown. It may be ...

To learn more about these small ear muscles, Hackley and colleagues recruited 20 participants with normal hearing and attached electrodes to their scalp to track electrical activity in their ...

Some researchers suggest that dysfunctional contractions of the muscles in the middle ear can cause fluttering sounds. Doctors call this rare condition middle ear myoclonus (MEM). MEM is a ...

The auricular muscles helped change the shape of the shell–or pinna–of the ear and helped humans living millions of years ago listen closely. They are still used by roughly 10 to 20 percent of ...

That's according to a new study which found that a certain vestigial ear muscle — one that perks up ears in animals — actually shows electrical activity when people engage in a difficult ...

It’s caused by a small muscle located in the middle ear called the tensor tympani (TT). The TT muscle tightens, or contracts, after you hear a very loud sound. This contraction muffles the ...

THE intensity of sound transmitted from the ear drum to the inner ear can be attenuated by contraction of the middle ear muscles, the tensor tympani and stapedius. These muscles contract at the ...
