AP PSYCHOLOGY

Detailed explanation-1: -The basilar membrane is a stiff structural element within the cochlea of the inner ear which separates two liquid-filled tubes that run along the coil of the cochlea, the scala media and the scala tympani.

Detailed explanation-2: -The organ of Corti (Figs. 14.11 and14.12) is a strip of hair cells and supporting cells about 35 mm long that rests on the basilar membrane.

Detailed explanation-3: -The basilar membrane is the main mechanical element of the inner ear. It possesses graded mass and stiffness properties over its length, and its vibration patterns have the effect of separating incoming sound into its component frequencies that activate different cochlear regions.

Detailed explanation-4: -The structure separating the scala tympani from the cochlear duct is known as the basilar membrane. The basilar membrane contains a specialized structure known as the organ of Corti that plays a key role in auditory transduction.

Detailed explanation-5: -At this distal apex of the cochlea, the basilar membrane is at its widest (approximately 0.5mm) and flaccid.
