parasympathetic nervous system part of autonomic systems, reverses effects of sympathetic nervous system on the body
sympathetic nervous system part of the autonomic system, causes symptoms such as accelerated heart and increased blood pressure, fight or flight reaction
spinal cord conveys sensory impulses to the brain from different parts of the body-transmits motor neurons away from brain to all muscles and organs
synapses small space found between axon and one neuron and the dendrite of another
Tay-Sachs disease genetic enzyme deficiency, progressive mental changes, paralysis, blindness, inability to each and ultimately death by age of four
