Can rigor set in before death?
Yes, although, everything I've read says NO. But my father died in my home and rigormortis set in prior to his death. Approximately 2 hours before death. My father was still alive, breathing, heart beat, pulse and his neck and head were totally stiff. I have yet to find any medical answers to back this up but witnessing it was real..He was completely stiff within 30 min of death. He died from bladder cancer..He did have alot of bleeding weeks prior to death which would mean he had lost a lot of blood. Not sure if that had anything to do with the early onset of rigormortis or not.
Why do people stiffen when they die?
It is called rigor mortis, and it is a temporary condition in cadavers that starts about 3 hours after death. It becomes most strong about 12 hours after death and weakens after that until about 72 hours after death. Afterwards the limbs loosen again and can be moved. See link for more.
What makes rigormortis cease after 72 hours?
The myosin heads detach from actin, allowing the muscles to relax; prior to rigor mortis, Directly after death ATP is not produced therefore, Ca +2 is absent within the myosin binding sites on the actin, which leads to the myosin heads not being able to detach from actin, this condition doesnt allow the muscle to relax, aka rigor mortis. For the muscle to relax or for rigor mortis to cease the myosin heads detach from actin.
Do eyes stay open after death?
I've heard they can fall open because of gravity that's why mortitions sew them shut. When a person dies, all of their muscles relax. If the eyes are open at the moment of death, they will usually stay that way. Also, if someone had their eyes closed at the moment of death, they will tend to open a short time later due to the relaxation of the muscles that open and close the eyes. This isn't always the case, but for the majority of people, the eyes will be open. Morticians do not sew the eyes shut. The old fashioned way was to take some cotton and place it under the eyelids. This kept them shut and gave them shape, as the eyes tend to sink back into the sockets after death. The current method of keeping the eyes closed is to use what are called eye caps. They have little grippers on one side, and are smooth on the other. The grippers keep the lids closed.
