Document Summary

Neuron dendrite: receive information from other neurons comes from greek word for tree cell body: keeps neuron alive and preforms maintenance task axon: transmits information away from the cell high way of nervous system. Myelin sheath: fatty material of glia cells gives faster neural impulses nodes: in between glia cells on axon glia cells look like sausages on axon impulse jumps from node to node. Action potential: electrical impulse travels along axon all or none from neuron to neuron ex. Resting potential: neuron is inactive synapse: junction where information is transmitted from one neuron to another axon terminal: bulb. Synaptic cleft: gap between neuron and dendrite dendrite: receptor site of dendrite synaptic vesicles: small sacs that store neurotransmitters chemicals that go from one neuron to the next. Lock and key: neurotransmitters go from dendrite and ts in receptor sites on neuron. Reuptake: the presynaptic neuron sponges up leftover neurotransmitters to recycle. Drugs: prevent this from happening or release more neurotransmitters.
