Question

question 2 of 10
sound vibrations are converted into nerve impulses in the:

a. cochlea.

b. ossicles.

c. eardrum.

d. auditory cortex.

Explanation:

To solve this, we analyze each option:

• Option B (ossicles): These are tiny bones in the middle ear that transmit sound vibrations but don't convert them to nerve impulses.
• Option C (eardrum): It vibrates in response to sound but doesn't convert to nerve impulses.
• Option D (auditory cortex): This is in the brain and processes auditory information, not where the conversion to nerve impulses happens.
• Option A (cochlea): The cochlea is part of the inner ear and contains hair cells that convert sound vibrations into nerve impulses.

Answer:

A. cochlea.
