Question
Chapter 10, Problem 9CP
Summary Introduction
 To review:
The effect of basilar membrane movement on hair cells and the mechanism used by hair cells to stimulate associated sensory organs.
 Introduction:
Once the sounds of different frequencies reach the basilar membrane, they stimulate the hair cells and the associated sensory neurons. Hair cells are made up of stereocilia. The position of the inner hair cells in the basilar membrane determines the sensitivity of the response to sound.
