Question

What is the chain of small bones in the ear called?

1) Malleus, Incus, Stapes
2) Cochlea, Vestibule, Semicircular canals
3) Tympanic membrane, Oval window, Round window
4) Eustachian tube, Auditory nerve, Cochlear duct

Answer 1

The chain of small bones in the ear is called the ossicles, which include the malleus, incus, and stapes. These bones transfer sound vibrations from the eardrum to the cochlea.

Step-by-step explanation:

The chain of small bones in the ear is called the ossicles. Specifically, the three small bones in the middle ear are named the malleus (hammer), incus (anvil), and stapes (stirrup). These ossicles transfer sound vibrations from the eardrum to the fluid-filled cochlea in the inner ear, where the sound signals are converted into electrical signals and sent to the brain for interpretation. The chain of small bones in the ear is called the ossicles. These are three tiny bones known as the malleus (or hammer), incus (or anvil), and the stapes (or stirrup). When sound waves reach the ear, they cause the eardrum to vibrate. These vibrations are transferred from the eardrum to the malleus, then to the incus, and finally to the stapes. The stapes then passes the vibrations into the inner ear, specifically to the fluid-filled cochlea, initiating the process that leads to sound perception. The correct answer to the question is option 1) Malleus, Incus, Stapes.
