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. So let's see how this signal actually takes place. So let's suppose I apply pressure onto my finger. As I apply the pressure, the dendrites of our sensory neuron contains special pressure receptors.
