This second easy-level Forensic Medicine mock covers a completely different set of foundational topics — zero repetition from Easy Mock 1 — spanning burns, head injuries, asphyxia types, forensic identity, infant deaths, and key legal principles. All thirty questions are at the definitional level. Questions cover: burn depth classification (second degree = epidermis + partial dermis = blisters + painful), ante-mortem vs post-mortem burns (soot in airways + CO-Hb + protein in blister fluid = ante-mortem), electrical mark characteristics (pale dry crater-like depression with upraised margins), Lichtenberg figures in lightning strike (branching fern-like marks; pathognomonic; transient), smothering (nose + mouth covered; minimal autopsy findings; difficult in infants), choking/café coronary (internal foreign body in airway; sudden death mimicking cardiac arrest), traumatic/crush asphyxia (chest compressed externally; intense face and neck petechiae), SIDS (under 1 year + unexpected + unexplained = diagnosis of exclusion), Shaken Baby Syndrome triad (subdural haemorrhage + retinal haemorrhage + encephalopathy), dying declaration (Section 26 BSA 2023; expectation of death; admissible without cross-examination), sexual assault examination components (head-to-toe + swabs + trace evidence + documentation), spermatozoa survival times (motile up to 6–12 hours; non-motile up to 3–5 days vagina), extradural haemorrhage (skull to dura; middle meningeal artery + temporal fracture; lucid interval), subdural haemorrhage (dura to arachnoid; bridging veins; no skull fracture needed), subarachnoid haemorrhage (arachnoid to pia; berry aneurysm; thunderclap headache), depressed skull fracture (focal blunt force; patterned weapon impression; skull driven inward), skeletal sex determination (pelvis most reliable at 95%+; obstetric differences), dental age estimation (eruption sequence for children; Gustafson's 6 criteria for adults), stature estimation from bones (femur + tibia + regression formulae; population-specific), expert witness role (duty to court; independent; impartial; not advocate), diatom test in drowning (bone marrow diatoms = alive when drowned; systemic distribution by heartbeat), hypothermia autopsy findings (cherry-red skin + Wischnewski spots + paradoxical undressing), hesitation cut vs defensive wound location (flexor wrist = self-inflicted; dorsal forearm = defensive), infanticide definition under Section 101 BNS 2023 (mother + child under 12 months + live birth), positional asphyxia (body position prevents breathing mechanics; airway open), adult skeletal age estimation (clavicle fusion + pubic symphysis phases + rib sternal end), thanatology definition (scientific study of death; causes + process + signs + post-mortem changes), corpus delicti in homicide (death occurred + criminal means; PM report is primary medical contribution), contrecoup injury (brain injured opposite the impact; head moves into stationary surface), and hydrostatic test for live birth in infanticide (lungs float = breathed = live birth). Themes covered: - Thermal and electrical injuries: burn depth, ante-mortem vs post-mortem burns, electrocution, lightning - Asphyxia variants: smothering, choking, traumatic, positional - Special deaths: SIDS, SBS, hypothermia, infanticide - Head injuries: EDH, SDH, SAH, depressed fracture, contrecoup - Identity and anthropology: skeletal sex, age from teeth, age from bone, stature estimation - Sexual assault: examination components, spermatozoa survival - Legal medicine: dying declaration (BSA 2023), expert witness, corpus delicti, infanticide (BNS 2023) Each question cites Nandy's Principles of Forensic Medicine.

This easy-level mock covers the foundational vocabulary, core concepts, and essential principles of forensic medicine that every NFSU MSc and FACT candidate must master. All thirty questions are pitched at the definitional level. Questions cover: definition and scope of forensic medicine (medicine + law; living and dead; injuries + court testimony), cause of death and its documentation in the MCCD (Part I causal chain; Part II contributory conditions), post-mortem lividity/livor mortis (gravitational blood settling; fixed at 6–12 hours), rigor mortis onset sequence (Nysten's law: face and jaw first, lower limbs last), post-mortem interval definition (time since death; estimated from multiple methods; always a range), algor mortis (body cools ~1°C per hour; Rule of Thumb; Henssge nomogram), manner of death classification (homicide + suicide + accident + natural + undetermined), asphyxia definition and signs (oxygen deficiency; petechiae + cyanosis + congestion + right heart dilatation), Tardieu spots location (conjunctivae + pleura + pericardium + facial skin), strangulation types (ligature strangulation vs manual/throttling), hanging definition (body weight as constricting force; angled ligature mark), hanging vs strangulation ligature mark differences (oblique + gap vs horizontal + complete), drowning autopsy findings (frothy fluid + emphysema aquosum + diatom test + Paltauf haemorrhages), vital reaction (ante-mortem tissue response; haemorrhage + inflammation + healing), incised wound features (sharp edge; longer than deep; clean margins; no bridges), laceration vs incised wound (blunt force; irregular margins; tissue bridges; abrasion), contusion mechanism (blunt force; ruptured vessels; intact skin; extravasated blood), abrasion features (friction removes epidermis; serum; debris; direction shown), decomposition stages (fresh → bloat → active decay → advanced decay → skeletal), adipocere formation (wet + warm + anaerobic → fat saponification → grave wax), defence wound (hands + forearms; victim blocks weapon; alive and conscious), hesitation wound (shallow parallel cuts near deeper wound; suggests self-infliction), hyoid bone fracture significance (compressive neck force; occurs in strangulation + hanging + direct blow), carbon monoxide poisoning appearance (cherry-red skin from carboxyhaemoglobin), MCCD structure and purpose (Part I causal chain; Part II contributory; death registration), forensic entomology for PMI (blow fly developmental stages + temperature = minimum PMI), mummification (dry heat + circulating air = desiccation; shape preserved), inquest under Section 176 BNSS 2023 (Executive Magistrate inquiry; suspicious death; can order PM), stab wound features (deeper than wide; pointed instrument; external size ≠ depth), and medico-legal autopsy indications (ordered by police/magistrate; sudden + unnatural + suspicious + custodial). Themes covered: - Core definitions: forensic medicine scope, cause vs manner vs mechanism of death, MCCD - Post-mortem changes: livor mortis, rigor mortis, algor mortis, decomposition, adipocere, mummification - Asphyxia: types, signs, petechiae, strangulation, hanging, drowning, CO poisoning - Mechanical injuries: incised wounds, lacerations, contusions, abrasions, stab wounds, defence wounds, hesitation wounds - PMI estimation: all methods including forensic entomology - Legal framework: inquest (BNSS 2023), medico-legal autopsy indications, MCCD Each question cites Nandy's Principles of Forensic Medicine.
