Document Summary

Joins the soma and axon to collect the impulses before sending one down the cell. Surrounds some neurons to increase how efficiently it can carry an impulse; made of myelin. Contains the genetic instructions for the function of a cell. The gap between the terminal button of a neuron and the dendrite of another. Spreads the cell"s impulse out to reach other neurons. Links up to the dendrites of the next neuron in the chain. Level of excitement required to trigger an action potential. When a neuron sends info down the axon, aka a spike or an impulse. When + ions go out & cell returns to its state. Incapable of firing no matter how much excitatory stimulation it receives. Slightly more than normal; action potential requires more to be triggered but can happen. The neurotransmitters bind to these on the post synaptic neuron. Returns a neuron to its negatively charged resting state.
