What type of stimulus?", "Image ImageDescription": "Receptor neurons respond to specific stimuli (e.g. touch, temperature, pressure, tension, sight, hearing, chemical) All other neurons (interneurons, motor neurons) respond to neurotransmitters released by other neurons. What is a nerve impulse? A quick switch in voltage potential (charge difference) across the membrane that travels all the way along the axon of the neuron. Occurs due to flow of ions across the membrane. All \u2013 or - nothing.
