And so we have this interneuron that connects our sensory to our motor neuron. So once the electric signal is transmitted into the interneuron, it travels and eventually it synapses with the motor neuron. Now, the motor neuron once again begins in a central nervous system. So it begins in a spinal cord and it leaves the spinal cord from the front side, from the ventral side. And that's exactly why it leaves from the ventral side in this diagram and travels and it carries that electric signal back to some effector organ. So this is where the signal arrives and this is where the signal is received by that receptor.
