Question

question 3
the snail - shaped tube in the inner ear, where sound waves are converted into neural activity, is called the ______.
○ cochlea
○ incus
○ eardrum
○ pinna

Explanation:

To solve this, we analyze each option:

• "incus" is a middle - ear bone, not a snail - shaped tube in the inner ear.
• "eardrum" (tympanic membrane) is in the middle ear, not the inner ear, and it vibrates in response to sound but doesn't convert to neural activity here.
• "pinna" is the outer ear part (the visible ear), not related to inner - ear sound - to - neural conversion.
• "cochlea" is the snail - shaped inner - ear structure where sound waves are transduced into neural signals.

Answer:

A. cochlea
