- - - - fixed muscle length or no reduction occurs
        
        length of the muscle or ends of each other
        
        fixated – the muscle is only tensed
    - - the rate of shortening remains constant while the length of
        the muscle changes
    - - Kosentric
      - Eksentric
  - - - Action potentials across the cell membrane will be
      - propagated to the T tubules and sarcoplasmic reticulum
      - channel. Ca di cistern will open
      - Ca ions are released into the cytoplasm
      - Ca ion binds to Troponin C
      - causes the active site of the actin filament to open
      - The myosin head binds to actin
      - sliding process in muscle contraction
  - - - Calcium enters the cytosol
      - Form a complex (calmodulin)
      - Activate enzymes (phosphorylase)
      - Hydrolysis of ATP produces ADP +
      - pyruvate
      - Activate myosin
      - Binds to actin filaments (crossbridge)
  - - - Early Repolization
      - Plateu
      - Fast Repolization
      - Resting state
  - - - Activation of motor neurons
      - Release of transmitter (acetylcholine)
      - Binding of acetylcholine (acetylcholine nicotinicm)
      - Increase in Na+ and K+
      - An end plate potential is formed
      - An action potential is fired
      - Depolarization (T tubule)
      - Spread of Ca2+ to thick and thin filaments
      - Binding of Ca2+ (troponin)
      - Formation of cross-links (actin and myosin)
      - Shift of thin filaments on thick filaments (shortening
- - - - Sarkolemma
      - Sarkoplasma
      - Retikulum sarkoplasma
      - Mitokondria
      - Mikrofilamen
    - - Aktin
      - Myosin
- - - - Role of osteoblasts and
      - osteoclasts in bone
      - remodeling
