Muscles
The movement of the ossicles may be stiffened by two muscles. 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. These muscles contract in response to loud sounds, thereby reducing the transmission of sound to the inner ear. This is called the acoustic reflex or Tympanic reflex.

Famous quotes containing the word muscles:
“As the strong man exults in his physical ability, delighting in such exercises as call his muscles into action, so glories the analyst in that moral activity which disentangles.”
—Edgar Allan Poe (1809–1845)
“The indispensable ingredient of any game worth its salt is that the children themselves play it and, if not its sole authors, share in its creation. Watching TV’s ersatz battles is not the same thing at all. Children act out their emotions, they don’t talk them out and they don’t watch them out. Their imagination and their muscles need each other.”
—Leontine Young (20th century)
“What is this beast, she thought,
with muscles on his arms
like a bag of snakes?
What is this moss on his legs?
What prickly plant grows on his cheeks?
What is this voice as deep as a dog?”
—Anne Sexton (1928–1974)
