actoin potential

Back 27

postively charged impulse that sends an electrical signal along the length of a neuron's axon to a synapse

Front 28

mirror neuron

sympathetic nervous system

Back 41

branch of autonomic nervous system that has an arousal function on the body's internal organs, speeding up bodily processes and mobilizing the body
