Physiological actions of calcium

  • Neutrophil chemotaxis, lymphocyte activation
  • Membrane stability (antagonises the effect of Mg and K at the cell membrane so is useful in treating toxic effects of these two cations)
  • Clotting factor cascade
  • Neurotransmitter release
  • Muscle cell depolarisation, myocardial contraction and bone strength
  • Bone formation
