Integrating information: touching something cold and respond to it immediately, controlling muscles and glands, establishing and maintaining mental activity. Cells of nervous system: need to be able to labels neuron thing, neuroglia, endorphins cant cross the blood brain barrier, endorphins are related to morphine, cerebral spinal fluids = csf. Parts of the neuron: know different parts of this neuron, know the types of neurons. If you don"t have a myelin sheath information doesn"t travel like it should. Electrical signals: don"t have to know the picture on it. Action potentials: have to pass through there ranvier so that it doesn"t go up and down (important ro remember) Myelinated and unmyelinated axons: when people that have multiple sclerosis their myelin sheets have been damaged.
