Question

Name the three ear bones which helps to amplify the vibration inside human ears?

• A. Hammer, anvil and stirrup
• B. Hammer, anvil and pinna
• C. Pinna, hammer and stirrup
• D. Eardrum, hammer and pinna

Answer 1

The correct option is A Hammer, anvil and stirrup

Sound transfers to the ear canal from the outer part of the pinna and creates the ear to vibrate. The eardrum emits these vibrations to the middle bones, these three bones are hammer, anvil and stirrup, which amplifies the sound by many times (20 times). This sound is allowed inside the inner ear cochlea after this amplification.
