===Rigor Mortis===
−*Muscles remain biochemically active after the death of an animal
−*Following a period of relaxation, contraction and stiffening occurs
−*Due to deficiency of ATP releasing myosin heads from their binding sites at end of power stroke
−*Onset faster in ATP deprived animals (starvation, hunting, tetanus...)
−*May be absent in cachetic animals
−*Disappears due to autolysis or putrefaction
−*See [[General Pathology - Post-Mortem Change#Rigor Mortis|general pathology]]
