PDF-Compare the mechanisms producing action potentials at a sensory receptor and at a motor

In all sensory receptors the stimulus causes a change in membrane permeability causing a generator potential However many sensory r eceptors photoreceptors cochlear hair cells and vestibular hair cells do not produce action potentials as a result.
