So a ferric neuron basically means it carries it away from that receptor. So these types of neurons enter our spinal cord from the back side and that means from the dorsal side. So dorsal means from the back of our spinal cord. Now, what about interneurons? Well, intraneurons are basically simply those neurons that connect other neurons to one another. For example, we can have an inter neuron that connects a sensory to a motor neuron as we'll see in just a moment in our example of the simple reflex arc.
