Sensory neurons carry signals from the receptors in our body (e.g. thermal, pressure etc.) to the relay neurons, which are found in our spinal cord. Relay neurons then send signals along the spinal cord to the brain. The brain then processes the information and sends a signal back down the spinal cord, through the relay neurons. Relay neurons then sends signals to motor neurons, which will then affect the muscles' movements. Read more: What_does_neuron_cells_do
