A 23 year old male patient demonstrating severe face and arm muscle spasms…

- - - - pulminary embolism
    - - ventilator
  - - - convulsion
    - - LockJaw
  - - - brain damage
  - - - sepsis
  - - - inhibitory GABA blocked
        
        unable to stop muscle contractions
- - - - Structual
        
        Bipolar: Two extensions off cell body
        
        Multipolar: Multiple extensions off cell body
        
        Unipolar: One extension off cell body
      - Functional
        
        Interneurons: Conducts impulses within the CNS/ Processing=
        
        Motor: Carry impulses away from CNS to muscle, glands, organs
        
        Sensory: Transmit impulses from sensory receptors to CNS
    - - Spatial
        
        EPSP are generated at different locations
        
        Two EPSPs from different location add together to hit threshold
        
        Multiple presynaptic neurons fire in unison
      - Temporal
        
        Two EPSPs add together and depolarize membrane
        
        Threshold is reached
        
        Rapid fire presynaptic neuron has EPSPs close in time
    - - Calcium Binds to Troponin
      - Tropomyosin unblocks myosin binding site on actin
      - Chemically gated sodium channels open
      - Neuron releases ACh
      - Voltage gated calcium channel opens
      - Stimulus received by neuron
  - - - Structural
      - Functional
    - - Spatial Summation: Multiple neurons sending multiple messages
      - Temporal Summation: Same neuron sending multiple messages
