So the motor neurons leave from the front side, the ventral side. But the sensory neurons pick up those signals and carries them through the backside into our spinal cord. The backside is the dorsal side. Now, one major difference between the sensory neurons and the motor neurons of our somatic system is the cell body of our motor neuron is found inside our spinal cord. But the cell body here is found close in the backside, so close to the backside of our spinal cord. So this region where we find the cell body of the sensory neuron is known as the dorsal or backside, so dorsal root ganglia, where ganglia simply means neurons outside of the spinal cord and the brain.
