WebComponents of a Reflex Arc The Stimulus. In the above example, the stimulus is the contact with the hot pot. This contact causes a nerve impulse that will travel to the spinal cord via the sensory neurons. Another example of a stimulus is an object (e.g. an insect) approaching your eye causing you to blink before you know it. WebMost reflex arcs involve only three neurons. The stimulus, such as a needle stick, stimulates the pain receptors of the skin, which initiate an impulse in a sensory neuron. This travels to the spinal cord where it passes, by means of a synapse, to a connecting neuron called the relay neuron situated in the spinal cord.
