connect your body to your brain (somatic and autonomic)
somatic nervous system
voluntary movement
autonomic nervous system
, all things your body does automatically
sympathetic nervous system
stress nervous system, (fight or flight response) speeds up everything escept digestion
parasympathetic nervous system
peace nervous system, returns you back to homeostasis
neuron
