somatic nervous system (sns)
it stretches nearly throughout your whole entire body
the nerves in this system delivers information from your senses to your brain
a subdivision of the peripheral nervous system
it carries around commands from your brain to your muscles so you can move around
central nervous system (cns)
it is one of two parts of the nervous system
it's job is to take in sensory information, process information, and send out motor signals
the central nervous system is made up of the brain and spinal cord
sympathetic nervous system (sns)
sympathetic neurons have cell bodies located in the intermediolateral columns, or lateral horns, of the spinal cord
activated during exercise, excitement, and emergencies. "fight, flight, or fright."
