So let's suppose my stimulus is that hot stove. So I place my hand on a hot stove. That stimulus is transformed into an electrical signal that is picked up by our sensory neuron of the somatic nervous system. It travels from the backside, the dorsal side of our spinal cord, and let's say it basically synapses first with an inter neuron. If it's synapses with an inter neuron, that means we have one synapse here. Now, eventually, the inter neuron shown in brown, found inside the spinal cord will synapse with our motor neuron of a somatic nervous system.
