AP PSYCHOLOGY

Detailed explanation-1: -The hair cells of the organ of Corti are arranged in four rows along the length of the basilar membrane. Individual hair cells have multiple strands called stereocilia.

Detailed explanation-2: -The auditory receptor cells, called hair cells, lie embedded within the basilar membrane. This membrane divides the spiraled cochlea into upper and lower chambers. Movement of the fluid within the cochlea causes stimulation of the hair cells.

Detailed explanation-3: -Hearing is an amazing process, and it’s all thanks to the 15, 000 or so tiny hair cells inside our cochlea-the small, snail-shaped organ for hearing in the inner ear. The cells are called hair cells because tiny bundles of stereocilia-which look like hairs under a microscope-sit on top of each hair cell.

Detailed explanation-4: -Cochlear Transduction. The OHCs within the organ of Corti amplify the basilar membrane movement (traveling wave), whereas the IHCs act as mechanosensory transducers, converting the mechanical energy into synaptic currents that drive the primary auditory neurons that synapse at their base.
