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

- - - - simple contraction, single action potential
    - - ACh released and binds on sarcolemma
    - - motor neuron and all muscle fibers supplied
    - - two stimuli received by muscle in rapid succession
    - - attaches to the cell membrane.
      - releases the vesicle contents outside the cell.
      - Vesicles containing molecules are transported from cell to the cell membrane.
    - - spastic paralysis
    - - Acetylcholine
    - - Produces Tetanolysin toxin
        
        effects neurons and the ability to produce neurotransmitters
      - causes muscle to contraction
        
        muscle spasms
    - - release of ACh neurotransmitters into synaptic cleft
      - Na+ enters resulting in end plate potential
      - calcium enters motor neuron
      - ACh diffuses across to Ach receptors on sarcolemma
      - AP arrives at axon terminal
      - Acetylcholinesterase degrades ACh
    - - events at neuromuscular juntion
        
        muscle fiber excitation
        
        excitation-contraction coupling
        
        cross bridge cycling
    - - respiratory
      - nervous
      - muscular
      - integumentary
    - - generation of end plate potential
        
        depolarization
        
        repolarization
    - - generation and propagation of AP
    - - restoration of resting conditions
    - - contraction period
      - relaxation period
      - latent period
    - - muscular paralysis
    - - isotonic contraction
      - isometric contraction
      - concentric contraction
      - eccentric contractions
    - - Working stroke
      - cross bridge detachment
      - Cross bridge formation
      - cocking of myosin head
  - - - Frequency stimulation
        
        number of muscle fibers stimulated
        
        relative size of fibers
        
        degree of muscle stretch
        
        are 80%-120% their normal resting length= more force
        
        if greater than 120% filaments do not overlap

        bulkier the muscle, the more tension
        
        muscles increase in size with exercise
        
        more motor units recruited, the greater force
        
        higher frequency, greater force
    - - fast oxidative fibers
        
        fast glycolytic fibers
        
        short term intensity
        
        hitting a baseball
        
        medium intensity
        
        sprinting and walking
      - low intensity
        
        maintaining posture
