| Back | How mechanoreceptor converts stimuli into impulse/action potential - at resting state, the stretch mediated Na+ channels too narrow for Na+ to enter, so neurone at resting potential - pressure changes shape of pacinian corpuscle, stretching the membranes surrounding the neurone, and so the stretch mediated Na+ channels widen and Na+ can diffuse in - infux of Na+ changes potential of membrane (depolarised), creating a generator potential, which creates an action potential (electrical impulse) |
