The stimulation of auditory nerves depends on the opening and closing of channels in the auditory hair cells. Which type of gating mechanism do these cells use?
(a) voltage-gated
(b) extracellular ligand-gated
(c) intracellular ligand-gated
(d) stress-gated
(d) Sound waves cause vibrations of the tectorial membrane. These vibrations cause the bundles of stereocilia to tilt. This tilting physically pulls the filament that links a cilium to the ion channel in neighboring cilia, which then pulls the gate on that ion channel open.
