• medium

• compression

A thin layer of skin stretched tight in the ear. It vibrates in response to soundwaves _____

• Cochlea

• Eardrum

• Stereocilia

• Stapes

Contains fluid that transfers vibrations along the basilar membrane, which has different areas that correspond to where different pitch sounds are detected.

• Eardrum

• Cochlea

• Stereocilia

• Stapes

Detector like hair cells that vibrate depending on the sound. They send signals to nerve cells that relay the information to the brain.

• Eardrum

• Cochlea

• Stereocilia

• Stapes
