Neurotransmitters are chemicals that transmit messages from one nerve cell (neuron) to another. The nerve impulse travels from the first nerve cell through the axonâa single smooth body arising from the nerve cellâ to the axon terminal and the synaptic knobs.
Pain messages travel along the peripheral nervous system until they reach the spinal cord. The gate control theory proposes that there are gates on the bundle of nerve fibers in the spinal cord between the peripheral nerves and the brain.These spinal nerve gates control the flow of pain messages from the peripheral nerves to the brain.ain messages may also be directed along a variety of pathways in the brain. 1  For instance, a fast pain message (A-delta fiber) is relayed by the spinal cord to specific locations in the brain, namely the thalamus and cerebral cortex.
