Quizplus · Accepted Answer

The basilar membrane is the thin, flexible membrane in the cochlea of the inner ear that determines pitch selection. It contains hair cells that are responsible for detecting sound vibrations at specific frequencies, and these hair cells send signals to the brain that are interpreted as sound. The other structures listed, such as the tectorial membrane, ear drum, scala tympani, and middle ear bone, all play important roles in hearing but do not determine pitch selection.
