A 23 year old brought in emergency, because of severe arm and face muscle…

- - - - It protects body organs and provide framework of muscles which causes movement
    - - Allow manipulation of environment, facial expression and locomotion.
    - - It includes skin, hair and nails, protects external body covering
    - - Responds to internal and external changes, activates muscles and glands.
  - - - It forms when successive stimuli adds together and produce strong muscle contraction
    - - Condition formed by muscular spasms that caused by malfunction of parathyroid gland and deficiency of calcium.
    - - Simple contractions result by a muscle fiber's response to single action potential
        
        Phases of muscle twitch
        
        Period of relaxation
        
        Tension declines to zero
        
        Latent period
        
        No muscle tension
        
        Period of contraction
        
        Tension increases
  - - - Produces a toxin that causes spastic paralysis
      - Open would with soil prone develops C.tetani infection
      - Block release of inhibitory neurotransmitter in NMJ
    - - Produces a toxin that causes muscular paralysis
      - Prevention of ACh in synaptic knob
      - Most cases caused from the ingesting toxin in canned foods
  - - - AP crosses from neuron to muscle cell through the neurotransmitter Acetylcholinen(ACh)
        
        The chemical . message, a neurotransmitter called ACh, binds to receptors on the outside of muscle fibers
