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: -Cochlea: Coiled, bony, fluid-filled tube in the inner ear that transforms sound vibrations to auditory signals.

Detailed explanation-3: -Of all the organs in the body, the cochlea secretes the most unusual extracellular fluid, endolymph, and generates the largest transepithelial voltage, the endocochlear potential – all to enable and sustain the most impressive mechanoreceptor, the hair cell.

Detailed explanation-4: -Cochlea. a coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses.

Detailed explanation-5: -The cochlea is a hollow, spiral-shaped bone found in the inner ear that plays a key role in the sense of hearing and participates in the process of auditory transduction. Sound waves are transduced into electrical impulses that the brain can interpret as individual frequencies of sound.
