area of skin connected to a particular spinal nerve
chemicals a body produces to decrease pain, attach to same receptors as morphine/opiates
assumption that stimulation of certain nonpain axons in the skin or in the brain can inhibit transmission of pain messages in the spinal cord
systems responsive to opiate drugs and similar chemicals

periaqueductal gray areas
area of the brainstem that is rich in enkephalin synapses (which produce optiate effects

three canals within the inner ear that contain specialized receptor cells that generate nerve impulses with body movement
