        H zone
        
        middle region where only thick filaments are present
        
        A bands
        
        zone includes thick filaments and where thin filaments overlap with them
        
        darker bands
        
        I bands
        
        region containing only thin filaments

        sarcoplasmic reticulum
        
        smooth endoplasmic reticulum
        
        stores calcium in a resting muscle cell
    - - dense regular connective tissue
        
        atttaches muscle to bone
  - - - 2.Initiation and propagation of an action potential along sarcolemma and T-tublules
        
        3.Release of Ca2+ from sarcoplasmic reticulum
        
        action potential propagated along t tubules stimulate voltage sensitive Ca2+ channels
        
        trigger opening of Ca2+ release channels located in sarcoplasmic reticulum
        
        first voltage gated Na+ channels open, Na+ moves in to cause depolarization
        
        second, voltage gated K+ channels open, and K+ moves out to cause repolarization
      - binding of ACh to ACh receptors trigger opening of voltage-gated ion channels
        
        Na+ rapidly diffuses into muscle fiber
        
        EEP reached once sufficient Na+ enters motor end plate
        
        membrane potential changes from -90mV to -65mV
  - - - needed to produce ATP
        
        required for the release of myosin head from binding site on actin
    - - needed in order to trigger muscle contraction
    - - needed for muscle growth and repair
    - - aids in calcium resoption
    - - needed in aerobic cellular respiration
- - - - lack of ATP
        
        inability to release myosin heads from binding sites on actin, leaving the muscle in a contracted state
  - - - inability to grow and repair muscle
- - - - high risk to fractures
        
        inability to heal or slowed healing of fractures
  - - - systems will eventually start to shut down and organ failure will occur
        
        death can occur if not fixed
      - immune system effected
        
        higher risk to infection or illness
