AP PSYCHOLOGY

Detailed explanation-1: -The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25, 000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.

Detailed explanation-2: -14.13C). Because the organ of Corti (which contains the auditory receptor cells) rests on the basilar membrane, different receptor cells respond best to sounds of different frequencies.

Detailed explanation-3: -Your cochlea is the hearing organ. This snail-shaped structure contains two fluid-filled chambers lined with tiny hairs. When sound enters, the fluid inside of your cochlea causes the tiny hairs to vibrate, sending electrical impulses to your brain.

Detailed explanation-4: -The cochlea is filled with two fluids (endolymph and perilymph), inside the cochlea is the sensory receptor-the Organ of Corti-which contains sensory cells with hair-like structures (hair cells) that are the nerve receptors for hearing.
