Question

The damage to ear by sudden explosion (loud sound) is prevented by

• A. Eustachian tubes
• B. Tensor tympani muscles
• C. Stapedius muscles
• D. All of the above

Answer 1

The correct option is D All of the above

Tensor tympani are the muscles located in the ear above the osseous portion of the auditory tube. The role of these muscles are to dampen the sound or vibrations produced by chewing. Thus, the muscles are involved in the reduction of the perceived amplitude of sounds. The stapedius muscles are similar in function to the tympani muscles. They reduce the amount of sound entering the inner ear. The function of these muscles along with the eustachian tube is to protect the internal ear form loud noises.

So, the correct answer is option D.
