Question 3

hair cells

Answer 3

The hair cells are mechanoreceptors with stereocilia that are stimulated by movement of the basilar membrane relative to the tectorial membrane. The stereocilia bend which results in opening of ion channels in the plasma membrane of the hair cell, depolarising the membrane and creating a receptor potential. Hair cells release an excitatory neurotransmitter when depolarised, which leads to excitation of cochlear afferent neurons, which make up the nerve fibres of the cochlear nerve.
