Foundations: Forensic Medicine, Courts, Ethics
What forensic medicine actually does inside the criminal-justice system: the history and scope of the discipline, the medico-legal expert's role in court (BSA 2023 § 39 / Daubert / Frye / R v. Turner 1975 admissibility, the Bolam-Bolitho standard), and the ethical frame (Helsinki Declaration, India's NMC Code, AMA, GMC Good Medical Practice).

Thanatology: Modes and Manner of Death
The conceptual backbone of every medico-legal case: definitions of death (brain death, cardiopulmonary, molecular), the cause / mechanism / manner trichotomy, the NAME five-manner classification (natural, accidental, suicidal, homicidal, undetermined), and the global frameworks (Indian BNSS 2023 inquest, US ME vs Coroner systems, UK Coroner inquest) that decide which deaths require an autopsy.

Post-mortem Changes and Time Since Death
The continuous biochemical and morphological cascade after death and the methods that read time off it: primary changes (algor / livor / rigor mortis with the Henssge nomogram and Newton's cooling model), decomposition (putrefaction, adipocere, mummification, skeletalisation), and instrumental + biochemical TSD methods (vitreous K+, gastric emptying, supravital reactions, entomology overlap).
