Forensic Medicine: rapid revision one-liners for NEET PG
Forensic Medicine (FMT) in NEET PG tests your knowledge of thanatology (death and its changes), toxicology, medico-legal procedures, identification and clinical forensic medicine. The subject is highly factual and rewards precise recall.
These one-liners cover the classic associations, time-based changes after death, poison-antidote pairs and medico-legal definitions that form the core of FMT questions.
Must-know one-liners
- Rigor mortis begins 1-2 hours after death, is fully established by 12 hours and disappears by 24-36 hours
- Rigor mortis follows Nysten rule: starts in jaw/face, then neck, trunk, upper limbs and finally lower limbs
- Cadaveric spasm (instantaneous rigor) occurs at the time of death; it has medico-legal significance as it cannot be reproduced after death
- Algor mortis is the cooling of the body after death; the body cools at approximately 1.5 degrees F per hour initially
- Livor mortis (post-mortem lividity) becomes fixed after 6-8 hours
- Marbling of the skin is due to post-mortem haemolysis and bacterial decomposition of blood in superficial veins
- Adipocere (saponification) is the conversion of body fat to a waxy substance; occurs in moist environments, takes weeks to months
- Mummification is desiccation of the body; occurs in hot, dry environments
- Casper dictum: decomposition in air is twice as fast as in water and eight times as fast as in soil (1:2:8 ratio)
- The most reliable method of identification is DNA fingerprinting (also dental records for mass disasters)
- Diatom test is used to differentiate ante-mortem from post-mortem drowning; diatoms are found in bone marrow in true drowning
- Dry drowning (laryngospasm without water aspiration) accounts for 10-15% of drowning deaths
- Cafe coronary is death due to choking on food, often mistaken for cardiac arrest
- Hanging: ligature mark in hanging is oblique, non-continuous and above the thyroid cartilage; in strangulation it is horizontal and continuous
- Judicial hanging causes fracture-dislocation of C2 vertebra (hangman fracture)
- Le Facie sympathique (unilateral miosis and flushing) is seen in partial hanging due to sympathetic trunk compression
- Tardieu spots (petechial haemorrhages) are seen in death due to asphyxia, especially on visceral pleura and epicardium
- Bruise (contusion) is an extravasation of blood into tissues without a break in the skin; colour changes help estimate age
- Laceration has irregular margins, intact bridging structures (nerves, vessels) and is caused by blunt force
- Incised wound has clean-cut margins, no bridging, and is longer than deep
- Stab wound is deeper than it is long on the surface
- Hesitation cuts (tentative wounds) are seen in suicidal incised wounds, typically on the wrist or neck
- Bevelling of bone in gunshot wounds helps determine entry (internal bevelling) vs exit (external bevelling)
- Tattooing (stippling) in a gunshot wound indicates a close-range shot (15 cm to 60 cm); it cannot be washed off
- Contact wound shows muzzle imprint, soot in the wound track and stellate laceration over bone
- Locard exchange principle states that every contact leaves a trace
- Section 174 CrPC deals with the police inquest; Section 176 CrPC deals with the magistrate inquest
- Section 304A IPC deals with death due to negligence (not amounting to culpable homicide)
- Res ipsa loquitur means the thing speaks for itself -- the negligence is self-evident
- Therapeutic privilege allows a doctor to withhold information if disclosure would harm the patient
- Corpus delicti means the body of the crime -- the facts proving that a crime has been committed
- Cyanide poisoning causes bitter almond smell; antidotes are sodium nitrite + sodium thiosulphate (or hydroxocobalamin)
- Organophosphorus poisoning causes cholinergic crisis (SLUDGE: Salivation, Lacrimation, Urination, Defecation, GI cramps, Emesis); treated with atropine + pralidoxime
- Arsenic poisoning causes Mees lines on nails, rain-drop pigmentation and rice-water diarrhoea
- Lead poisoning causes wrist drop, blue line on gums (Burton line), basophilic stippling of RBCs and abdominal colic
- Mercury poisoning causes erethism (personality changes), gingivitis, tremor and Minamata disease (methyl mercury)
- Dhatura poisoning causes anticholinergic symptoms (dry, hot, red skin, mydriasis, tachycardia)
- Oleander (Nerium) poisoning causes cardiac glycoside effects (bradycardia, heart block)
- Abrus precatorius (Indian liquorice) contains abrin, one of the most toxic plant poisons
- Aconite (Vatsanabha/monkshood) is considered the queen of poisons; causes tingling and cardiac arrhythmias
- Vitriolage refers to acid throwing; Section 326A IPC deals with voluntarily causing grievous hurt by acid attack
- Run-over injuries show tyre marks, grease marks and characteristic pattern of bumper impact
- Age estimation in children uses dental eruption, ossification centres and epiphyseal fusion
- The first permanent tooth to erupt is the first molar at 6 years
- Gustafson method of age estimation uses six dental parameters including attrition, periodontosis and cementum apposition
- Infanticide: live birth is established by hydrostatic test (lung floats if breathing occurred), though it has limitations
- Precipitin test is used to determine whether a stain is of human origin
- Pugilistic attitude (boxer position) of a burnt body is due to heat coagulation of muscles, not ante-mortem struggle
- Dowry death is dealt with under Section 304B IPC; must occur within 7 years of marriage
- Section 375 IPC defines rape; Section 376 prescribes punishment for rape
How to use these one-liners
Forensic medicine one-liners lend themselves well to rapid-fire Q&A practice. Cover the second half of each statement and test your recall. Pay special attention to time intervals (rigor mortis, lividity fixation, decomposition) and poison-antidote pairs.
Group related concepts: all asphyxia types together, all poisons together, all legal sections together. This prevents confusion between similar entities in the exam.
Key mnemonics
SLUDGE for organophosphorus poisoning: Salivation, Lacrimation, Urination, Defecation, GI cramps, Emesis.
For lead poisoning -- LEAD: Lead lines on gums (Burton line), Encephalopathy, Anaemia with basophilic stippling, Drop (wrist/foot).
Nysten rule for rigor mortis onset: starts from the face downward (jaw first, lower limbs last).
Revision schedule
Forensic medicine is compact enough to revise in 2-3 focused sessions per week. Alternate between thanatology + identification and toxicology + medical jurisprudence. In the final week, one complete daily run-through is sufficient. Focus extra time on toxicology -- poison identification questions are among the most straightforward in the exam.
Frequently Asked Questions
How many FMT questions appear in NEET PG?
Typically 8-12 questions. Toxicology, post-mortem changes and medico-legal definitions are the most commonly tested. The questions are usually direct and factual.
Are IPC sections asked directly?
Yes, key sections like 304A, 326A, 375 (rape) and 176 CrPC appear regularly. You do not need to memorise every section -- focus on the 10-15 most commonly tested ones.
How important is toxicology for NEET PG?
Very important. Expect 3-5 questions on specific poisons, their clinical features and antidotes. Organophosphorus, arsenic, lead and cyanide are the most frequently tested.
Should I study forensic medicine from Reddy or Nageshkumar?
Reddy is the most comprehensive reference. For NEET PG, Nageshkumar or Sumit Seth provide more exam-focused coverage. One-liners are ideal for last-minute revision after reading the basics.
