Rigor morits takes place mostly because the muscles cannot relax after someone dies. The bones in a person's body start to actually contract within themselves and the skeletal muscles start to do the same.
A few hours after a person dies the joints of the body stiffen and become locked in place. Rigor mortis is caused by the skeletal muscles partially contracting. The muscles are unable to relax, so the joints become locked.
The proteins are beginning to break down, thus preventing a flow of calcium ions.
Mainly death
Temperature does effect rigor mortis. Low temperatures slow rigor mortis and it is accelerated by high temperatures.
The duration of Rigor Mortis - radio - is 1800.0 seconds.
Rigor Mortis Sets In was created in 1972-11.
Rigor mortis (literally "stiffness of death") is a natural process within the body after somatic death in which the skeletal muscles become locked in a contracted position. The carcass becomes rigid and unbending. Intoxication with a neurotoxin could affect the development of rigor mortis. For instance, tetanus toxin would cause the animal to be practically in rigor mortis at the time of death because it causes a spastic paralysis where the muscles are contracted during life. In contrast, botulinum toxin might cause the animal to have delayed rigor mortis or even to not develop a full rigor mortis because it blocks the nerves and causes a flaccid paralysis.

Short answer; yes.All muscles undergo rigor mortis at some time after death.
That is the correct spelling for "rigor mortis" -- a Latin phrase applied to the stiffening of muscle tissues after death.
Do not commence CPR if signs of rigor mortis or lividity are present.
