23 year old male brought to ER experiencing sever face and arm muscle…

- - - - Patient didn't practice proper after care
- - - - Toxin transports axonally to spinal cord and brain stem
        
        Toxin moves synaptically into inhibitory nerve terminals
        
        release of ACH at NMJ stops
        
        Vesicular release of inhibitory neurotransmitters is blocked causes disinhibition of lower motor neurons

  - - - Rapidly firing presynaptic neuron causes EPSP's that are close in time
        
        Two EPSP's close in time add together
        
        Axons initial segment brought to threshold and an AP fires
    - - More than one presynaptic neuron fires at the same time
        
        Two EPSP's from different locations fire simutaneously
        
        Axon brought to threshold and an AP fires
    - - Slow firing Presynaptic neuron causes EPSP's that are far apart in time
        
        Two EPSP's do not add together
        
        Threshold is not reached. No AP created
  - - - blocks neurotransmitter release
- - - - Lockjaw/ trismus
