- - - - Generates thoughts and Emotions
        
        memories are formed and stored
        
        PERIPHERAL Nervous system:
        
        Cranial & Spinal Nerves
        
        Sensory afferent Neurons carry info from body to CNS

    - - brings info from receptors in internal organs to CNS & motor neurons to SKELETAL MUSCLES, CARDIAC, & GLANDS
        
        involuntary portion of PNS
        
        SYMPATHETIC Nervous System:
        
        "fight or flight" responses
        
        PARASYMPATHETIC Nervous system:

  - - - Integrated Function- analyzes sensory information, stores some aspects, and makes decisions regarding behavior
        
        Motor Functions- respond to stimuli by starting muscular contractions or glandular secretion
- - - - Dendrites: receiving portions, branched
        
        Axon start: SINGLE fiber
        
        Myelin: acts as insulator, increases speed of impulse travel, gaps are called NODES of Ranvier
        
        Multipolar: SEVERAL Dendrites & ONE axon
        
        Bipolar: ONE dendrite, ONE axon
        
        Unipolar; sensory neurons, Ganglia
