Cell body- life support unit; controls the metabolic activity Dendrites-recieves impulses for the cell body(secretary) Axon-transmirs impulses away from the cell body(offers protection and serves as insulation of nerve impulses) 18. Saltatory conduction 19. Nodes of Ranvier 20. Salt moves in; Potassium moves out. 21. velocity up to 100-fold; 120 m/s 22. Depolarization-repolarization cycles. 23.Electrical- communication is continuous, impulse passes from one neuron to the next. Chemical- clefts exist that break the impulse; when the action potential reaches these terminal, it signals the release of neurotransmitters into the synaptic cleft. 24.Dopamine-Schizophrenia(Overproduction); Parkinson(Inhibatory; not enough) Epinephrine-Excitatory Norepinephrine-Excitatory Serotonin-inhibitory---> Depression(not enough) Histamine-Excitatory GABA-Inhibatory Glycine-Inhibatory Glutamate-Excitatory 25.pituitary peptides

In vesicles in the axon terminal and released by exocytosis 27.By its arrival pf the action potential in the axon terminal 28.Results in release of neurotransmitters into the synaptic cleft, where these molecules rapidly diffuse to interact with postsynaptic receptors 29. Reuptake 30. They take the neurotransmitters back into the intracellular compartment away from the synaptic cleft for vesicle repackaging or either they can be degraded (taken to the scrap yard) and their parts can be used for new neurotransmitter synethesis and storage.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
