AP PSYCHOLOGY

Detailed explanation-1: -The basilar membrane is also the base for the hair cells. This function is present in all land vertebrates. Due to its location, the basilar membrane places the hair cells adjacent to both the endolymph and the perilymph, which is a precondition of hair cell function.

Detailed explanation-2: -The basilar membrane is located on the base layer of the organ of Corti which is in the cochlea, and the cochlea is a fluid-filled structure in the inner ear.

Detailed explanation-3: -This action is passed onto the cochlea, a fluid-filled snail-like structure that contains the organ of Corti, the organ for hearing. It consists of tiny hair cells that line the cochlea. These cells translate vibrations into electrical impulses that are carried to the brain by sensory nerves.

Detailed explanation-4: -There are two types of sensory hair cells that reside on the basilar membrane; a single row of inner hair cells and three rows of outer hair cells. Both inner and outer hair cells contain up to 150 stereocilia protruding from their apical surface and are arranged in rows based on their height.

Detailed explanation-5: -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.
