Medicina Legal 07 - Fenômenos e Cronotanatognose | Conceitos fundamentais

This video covers the main fundamentals of Chronothanatognosis, the branch of Thanatology that studies the determination of the approximate time of death. We analyze in detail the chronological evolution of abiotic and transformative cadaveric phenomena, establishing time windows for each stage. We discuss Nysten's Triad (progression of rigor mortis), the evolution of hypostasis stains (fixation of livor mortis), and the gradual cooling of the body (algor mortis). We discuss the phases of putrefaction—colorative (abdominal green stain), gaseous (cadaveric emphysema), liquefaction, and skeletonization—and how environmental factors such as temperature and humidity accelerate or delay these processes. We also present concepts of forensic entomology and cadaveric fauna as aids in dating death, highlighting how the forensic expert uses these indicators to validate alibis and reconstruct the timeline of the crime. Essential content for students and those preparing for competitive exams who seek precision in the analysis of the post-mortem interval. #MedicinaLegal #Cronotanatognose #Tanatologia #FenomenosCadavericos #IntervaloPostMortem #PeritoCriminal #PoliciaCientifica #EstudoParaConcursos
