Re: Rigor Mortis In The Lower Limbs.
Rigor mortis occurs because the muscles contract and the joints become locked in place. Once death is evident, the body can no longer control the transport of calcium ions and thus they flow into the muscle cells and cause contraction. Moreover, the muscles require adenosine triphosphate (ATP) in order to relax a muscle contraction. This production of ATP is, obviously, halted in death and the muscles cannot relax until they themselves begin to decay (approximately 48-60 hours after death). |
