Detection of sound by the nervous system requires conversion of the auditory stimulus into an electrical signal. This is accomplished by the hair cells in the organ of Corti. The conversion process begins when a specific component of the hair cells moves in response to the vibration caused by an auditory stimulus. What is this component called?
a. Stereocilium
b. Tip link
c. Voltage gated calcium channel
d. Mechanically gated ion channel
