What is rigor mortis and how would the onset of rigor mortis differ depending on the kind of neurotoxin the animals were exposed to?
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.
Does a flaccid arm undergo rigor mortis?
Short answer; yes.All muscles undergo rigor mortis at some time after death.
How do you spell rigor mortis?
That is the correct spelling for "rigor mortis" -- a Latin phrase applied to the stiffening of muscle tissues after death.
How long after death does rigor mortis set in?
Provided there were no electrolyte or musculoskeletal abnormalities prior to death, the carcass should be in full rigor within 12 hours.
How is rigor mortis used to estimate the time of death?
Rigor mortis does not provide an exact time of death, as it will change depending on factors (such as temperature). However, because it generally follows a rough time range it may be somewhat useful. Usually begins 3hrs after death, reaches its maximum after about 12hrs and is not present after 72hrs. Therefore the degree of rigor mortis gives an estimated time of death.
Rigor mortis in mice?
Mice are warm blooded mammals like humans. After death their muscles are affected by rigor mortis in the same way.
What is it called when a body stiffens after death?
It depends on the climate that the body is in and the conditions. 2 or 3 hours after a person dies the muscles begin to get stiff. Maximum stiffness occurs at around 12-24 hours. "Rigor Mortis"

Can you eat an animal that died of rigor mortis?
Rigor mortice is the (temporary) stiffening of joints after death. Animals do not die of rigor mortice.
