| A | B |
| sodium potassium pump | 3 Na out, 2 K in; creates resting potential |
| gated sodium channel | open when threshold is reached causing depolarization |
| gated potassium channel | open after Na channel, increase depolarization, cause hyperpolarization |
| leaked potassium channel | maintain the resting potential by leting some potassium out |
| dopamine | neurotransmitter associated with pleasure, accomplished, reward |
| gaba | main inhibitory neurotranmitter, raises threshold |
| endorphin | neutrotransmitter associated with pain reduction, happy feeling |
| acetylcholine | main motor neurotranmitter |
| serotonin | neutrotransmitter associated with emotional stability |
| medulla | controlls involuntary reflexes like breathing, heart beating |
| pons | involuntary reaction, facial movement, swallowing, chewing |
| thalamus | relay center, coordinates the movement of signals through the brain |
| cerebellum | complex, coordinated movement |
| cerebrum | higher thought, consciousness |
| hypothalamus | regulatory center, homeostasis, hormone relay |
| frontal lobe | personality, problem solving, future planing |
| parietal lobe | touch, spatial perception |
| temporal lobe | memory, hearing, language |
| occipital lobe | visual processing, language/word recognition |
| limbic system | group of brain parts center of emotion, memory and motivation |
| amygdala | pleasure, pain center of the brain |
| autonomic nerve system | peripheral nerves that extend to the organs, cotrlols mostly automatic responses |
| somatic nerve system | peripheral nerves to the muscles, involved in voluntary responses |
| sympathetic system | the 'fight' or 'flight' state excites muscles, energy production, heart rate |
| parasympathetic system | the 'rest' and 'digest' state. excites the digestive system, inhibits the muscles, energy production |
