What term describes the prolongation of the last violent muscle contraction into death rigidity?

The term that describes the prolongation of the last violent muscle contraction into death rigidity is often referred to as cadaveric spasm. This phenomenon can occur in certain circumstances, typically when there are strong emotional or physical stresses at the time of death, leading to a temporary stiffening of the muscles. Unlike rigor mortis, which is a process that develops after death and involves the biochemical changes in muscle tissue, cadaveric spasm represents a more immediate and distinct muscular contraction at the moment of death or directly following it.

In forensic contexts, the identification of cadaveric spasm can help in understanding the circumstances surrounding a person's death, as it may indicate a struggle or sudden trauma. This makes it a significant term in both mortuary science and forensic investigations, adding depth to the understanding of how bodies respond post-mortem.
