Answer 1

Answer:

your answer is here !

Explanation:

Three tiny bones present in the middle of the ear are: Hammer, Anvil and Stirrup

Function:

(i) Hammer: This is the largest bone in the middle ear. It's attached to the inner side of the eardrum. When the eardrum vibrates due to the incoming sound waves, it causes hammer to vibrate which inturn passes these vibrations to the next bone, Anvil.

(ii) Anvil: Anvil which is located in between Anvil and Stirrup, passes the sound vibrations from Anvil to Stirrup.

(iii) Stirrup: The vibrating stirrup strikes on the membrane of the oval window and passes its vibrations to the liquid in cochlea which then produces electric impulses to be interpreted by the brain.
