- - - - multipolar
        
        many dendrites, one axon
      - bipolar
        
        one dendrite, one axon (sensory)
      - unipolar
        
        fused axon and dendrite (Sensory)
      - 3 types of Neurons
        
        Sensory transmit impulses to CNS
        
        Motor (efferent) transmit impulses away from CNS
        
        Interneurons yransmit impulses from sensory nuerons to motor neurons
  - - - astrocytes (CNS) 2. Oligodendrocytes (CNS) 3. Microglia (CNS)
        
        ependymal (CNS) 5. Schwann cells (PNS) 6. Satellite cells (PNS)
- - - - Sensory receptor 2. Sensory neuron 3. Synapse 4. Motor neuron
- - - - cell bodies of motor neurons to cardiac and smooth muscles and glands
    - - cell bodies of motor neurons to skeletal muscle
- - - - Brain, Spinal Cord recieve incoming sensory information
    - - All nerves that extend from brain and spinal cord
- - - - largest portion and associated with higher mental functions
      - 4 lobes of cerebrum
        
        Frontal
        
        personality, and emotions
        
        Temporal

        visions
    - - processes sensory input and controls many homeostatic processes
    - - coordinates and regulates visceral activities
    - - coordinates muscular activity
