Sensory cells transduce physical and chemical stimuli into neuronal signals. Sensory transduction: begins with a receptor protein that can detect a specific stimulus. The receptor protein opens or closes ion channels in the membrane, changing the resting potential. Hair cells are the sensory receptors of both the auditory system and the vestibular system in the ears of all vertebrates, and in the lateral line organ of fishes. Through mechanotransduction, hair cells detect movement in their environment.
