... 4. Vibration of the basilar membrane causes bending of the hair cells. This causes inner hair cell depolarization due to cation (mainly K+) influx (generator potential), followed by Ca2+ influx (due to opening of voltage-dependent Ca channels), leading to release of excitatory transmitter, causing a ...

Auditory system
The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system.
