AP PSYCHOLOGY

Detailed explanation-1: -The Organ of Corti is an organ of the inner ear located within the cochlea which contributes to audition. The Organ of Corti includes three rows of outer hair cells and one row of inner hair cells. Vibrations caused by sound waves bend the stereocilia on these hair cells via an electromechanical force.

Detailed explanation-2: -Once the vibrations cause the fluid inside the cochlea to ripple, a traveling wave forms along the basilar membrane. Hair cells-sensory cells sitting on top of the basilar membrane-ride the wave.

Detailed explanation-3: -The hair cells located in the organ of Corti transduce mechanical sound vibrations into nerve impulses. They are stimulated when the basilar membrane, on which the organ of Corti rests, vibrates.

Detailed explanation-4: -Sound vibrations create waves in the cochlear fluids. As the waves peak, they cause tiny hair cells to bend, which converts the vibrations into electrical signals. These tiny hair cells are called stereocilia (types of receptors that can detect sound).

Detailed explanation-5: -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.
