So sensory neurons are neurons that receive electrical signals from receptors and carry those to other neurons or to the central nervous system. Now, sensory neurons are also known as aphary neurons. So notice that we have an E here and we have an A here. 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.
