Cadaveric spasm

Rigor mortis and cadaveric spasm are two common postmortem conditions that often occur after the death of an individual. While the two are related in their nature, there are several key differences between the two that are important for medical professionals to be aware of. In this blog post, we will discuss the differences between rigor mortis and cadaveric spasm, and how they affect the human body after death. Rigor mortis, known as the “stiffness of death,” is an important post-mortem phenomenon that affects a deceased body. It is a natural process that begins to set in shortly after death, usually within 3-4 hours, and can last for up to 72 hours. It is caused by a chemical change in the muscles, which causes them to harden and become stiff. Rigor mortis is a common occurrence, and is a key factor in determining the time of death. On the other hand, cadaveric spasm, also known as instantaneous rigor, is a rare phenomenon that sets in immediately after death and can last for up to 24 hours. It is caused by the rapid contraction of the muscles due to an electrical discharge. It is most commonly seen in traumatic deaths where the body goes into a sudden spasm. Unlike rigor mortis, cadaveric spasm does not affect the entire body, but instead, is limited to the muscles involved in the last action the deceased performed prior to death. Definition of cadaveric spasm Cadaveric spasm, also known as instantaneous rigor mortis, is a phenomenon that occurs shortly after death and ...

What causes spasm? Muscle pain, fatigue, and overuse are the most common causes of muscle spasms. Other causes include stress or anxiety, which can lead to muscle twitches in the face. Trapped nerves can result in spasms in the back. What causes rapid rigor mortis? When oxygen is no longer present, the body may continue to produce ATP via anaerobic ...

A lot of novels state that a person died with a smile on the face, or how relatives/friends notice a smile on the face that remains even after death. Is such a thing anatomically possible? Will a smile or any other expression be retained by the muscles at/after death? (without external assistance from say a mortician) And which expression is most common at death? (once skin and muscles die, after death, during rigor and after rigor passes, when undisturbed) At the moment of death, contrary to what may common assumption, rigor mortis does not set in; at the moment of death „flattency“ sets in, which is relaxation of muscles, not fixation or arrested motion of muscles. See "At the time of death, a condition called "primary flaccidity" occurs. Following this, the muscles stiffen in rigor mortis. (...) Starting between two and six hours following death, rigor mortis begins with the eyelids, neck, and jaw. (...)" Counterintuitely, and this might be the key to the question, a smile on the face is not produced by relaxing one's muscles. To produce that gesture affords the contracting of several muscles. There are many search results on "smile muscle contraction" with Google's first page incidentally tells about Duchenne smile, too (nowadays presumably termed "resting b.... smile"): "All smiling involves contraction of the zygomatic major muscles, which lifts the corners of the mouth. But a Duchenne smile is characterised by the additional contraction of the orbicularis oculi, (.....

Abstract It has been occasionally observed in cases of sudden death after great and prolonged muscular tension and excitement that the body becomes instantaneously rigid in the position assumed at the moment of dissolution; thus a soldier is killed in action and remains fixed in the position of firing his piece, a lunatic after a prolonged period of excitement is found dead in the exact attitude of a convulsion or some other equally striking condition. Few have probably had the opportunity to observe this phenomenon, but its occurrence is incontestible though it has received little mention in physiologic or medico-legal treatises. Its explanation is not altogether easy on the usual theories of rigor mortis, notwithstanding the fact that the essential conditions are, in part at least, the same. There is the same muscular rigidity lasting a longer or shorter time and probably the coagulation of the myosin, which is assumed to • Academic Medicine • Acid Base, Electrolytes, Fluids • Allergy and Clinical Immunology • Anesthesiology • Anticoagulation • Art and Images in Psychiatry • Assisted Reproduction • Bleeding and Transfusion • Cardiology • Caring for the Critically Ill Patient • Challenges in Clinical Electrocardiography • Climate and Health • Clinical Challenge • Clinical Decision Support • Clinical Implications of Basic Neuroscience • Clinical Pharmacy and Pharmacology • Complementary and Alternative Medicine • Consensus Statements • Coronavirus (COVID-19) • Critical Car...
