I now have comprehensive textbook content. I have all the information needed to compile the complete set of definitions. Let me now write the full answer.
Here are the exact definitions for each term, sourced from the Essentials of Forensic Medicine and Toxicology (36th ed., 2026) and Parikh's Textbook of Medical Jurisprudence, Forensic Medicine and Toxicology, supplemented by DiMaio's Forensic Pathology (3rd ed.) and Forensic Anthropology: A Comprehensive Introduction (2nd ed.):

1. AUTOPSY

Autopsy (or necropsy) means the postmortem examination of a body after death. In every case the autopsy must be complete - all body cavities should be opened and every organ examined, because evidence contributory to the cause of death may be found in more than one organ.

2. MEDICAL AUTOPSY (Clinical Autopsy / Pathological Autopsy)

A clinical (pathological) autopsy is performed by a hospital pathologist who has access to the clinical history, physical condition, and course of disease leading to death. Its main aim is to find morphologic changes (extent of a known disease) explaining signs and symptoms of the disease and the effectiveness of treatment. It detects previously unrecognized or undiagnosed disease, helps the family know of inheritable conditions, and relies heavily on histologic assessment. It is academically oriented.

3. CLINICAL AUTOPSY

Same as medical/pathological autopsy (see above). It is performed in a hospital setting to correlate clinical findings with postmortem findings, determine the cause of death, and assess the extent of natural disease or comorbidities that led to death.

4. EXHUMATION

Exhumation is the legal digging out (disinterment) of an already buried body from the grave (burial of a dead body is called inhumation). There is no time limit for exhumation in India. It is authorized only on a written order from an Executive or Judicial Magistrate [Section 196(4), BNSS]. Autopsies on exhumed bodies are usually performed at the site of exhumation.

5. DEATH

Death is the permanent cessation of all vital functions - respiration, circulation, and brain function - that are necessary to sustain life. In forensic medicine, somatic (clinical) death refers to the cessation of the three vital signs (heartbeat, respiration, and brain activity), while molecular (cellular) death refers to the gradual cessation of metabolic activity in individual cells and tissues after somatic death.

6. ALGOR MORTIS

Algor mortis is the cooling of the body after death, from the average body temperature (98.6°F / 37°C) down to the ambient/atmospheric temperature, typically at a reduction of about 1.5°F (approximately 1°C) per hour under average conditions. It is one of the early postmortem changes used to estimate time since death.

7. RIGOR MORTIS

Rigor mortis is the stiffening or rigidity of muscles that occurs after death due to the depletion of ATP and the irreversible cross-linking of actin and myosin filaments. It usually begins 1-2 hours after death, becomes fully established in approximately 6-12 hours, and passes off (resolves) in 24-48 hours as the muscles undergo autolysis. It follows Nysten's law - appearing first in the muscles of the face and jaw, then descending to the neck, trunk, and lower limbs.

8. LIVOR MORTIS (Postmortem Lividity / Hypostasis)

Livor mortis is the purplish-blue discoloration of the skin caused by the gravitational pooling of blood in the dependent (lowest) vessels and capillaries after circulation ceases. It appears as reddish-purple staining in the skin over the dependent parts of the body. It begins approximately 30 minutes to 2 hours after death, becomes fixed (non-blanchable) after 6-12 hours, and is used to determine the position of the body after death and estimate the time of death.

9. DECOMPOSITION

Decomposition is the general process by which organic matter (including the human body after death) is broken down into simpler substances through biological, chemical, and physical processes. It begins immediately after death and includes autolysis (self-digestion by enzymes), putrefaction (bacterial breakdown), and further disintegration. It passes through stages: fresh, bloat, active decay, advanced decay, and dry/skeletal remains.

10. PUTREFACTION

Putrefaction is the decomposition or disintegration of tissues of the dead body by the action of bacteria (mainly anaerobic organisms such as Clostridium welchii) and other microorganisms, resulting in the liquefaction of soft tissues and the production of foul-smelling gases (hydrogen sulphide, methane, ammonia). The process converts complex organic compounds into simpler inorganic substances. It is marked externally by greenish discoloration of the abdomen (first sign in a temperate climate), followed by marbling, bloating, skin slippage, and ultimately skeletonization.

11. ADIPOCERE

Adipocere (from Latin: adeps = fat, cera = wax) is a modification of putrefaction. It is the formation of a soft, whitish, crumbly, waxy, and greasy material occurring in the fatty or fat-containing tissues of a dead body. The fatty tissues of the body change into a substance called adipocere through the process of hydrolysis and hydrogenation of pre-existing fats (olein, etc.) into higher fatty acids, which combine with calcium and ammonium ions to form insoluble soaps. It is seen most commonly in bodies immersed in water or in damp, warm environments, and it acts as a preservative, inhibiting further putrefaction.

12. MUMMIFICATION

Mummification is a modification of putrefaction in which dehydration (drying and shriveling) of the cadaver occurs from evaporation of water, while the natural appearances of the body and general facial features are preserved. The skin becomes dry, brittle, leathery, and rusty-brown to black in color. The entire body loses up to 60-70% of its weight. It occurs in hot, dry conditions with free circulation of air. A mummified body is practically odorless.

13. EMBALMING

Embalming is the preservation of the dead body by the introduction of antiseptic chemicals into the body tissues to temporarily prevent putrefaction and decomposition. It is done to preserve the body for transport over long distances, for delayed burial, for teaching/dissection purposes, or for public display. Common embalming fluids include formaldehyde, phenol, glycerin, and alcohol. It may interfere with toxicological analysis if performed before the medicolegal examination.

14. FINGERPRINT

A fingerprint is the impression left by the friction ridges (papillary ridges) of a fingertip on a surface. The patterns of ridges are unique to every individual and do not change throughout life. In forensic medicine, fingerprints are used for identification of living persons, deceased persons, and suspects. The three main patterns are loops (most common, ~60-65%), whorls (~30-35%), and arches (~5%). The science of fingerprint identification is called dactyloscopy.

15. CHEILOSCOPY (Lip Print Identification)

Cheiloscopy is the study and analysis of lip prints (impressions made by the lip mucosa) for forensic identification. The grooves and furrows on the lips (lip rugae) are unique to each individual and remain constant throughout life. Lip prints can be found on objects such as glasses, cups, cigarette butts, or envelopes. They are used as a supplementary method of personal identification.

16. ASPHYXIA

Asphyxia is a condition caused by interference with respiration, or due to lack of oxygen in the respired air, due to which the organs and tissues are deprived of oxygen (together with failure to eliminate CO2), causing unconsciousness or death. The term asphyxia indicates a mode of dying rather than a cause of death.

17. HANGING

Hanging is a form of ligature strangulation in which constriction of the neck is caused by a ligature (rope, cord, etc.) tightened by the weight of the body (or part of the body). The cause of death in hanging is primarily cerebral anemia (compression of carotid arteries), venous obstruction (compression of jugular veins), and reflex cardiac inhibition (stimulation of the vagus nerve and carotid sinus). Judicial hanging also causes fracture/dislocation of the upper cervical vertebrae causing cord transection.

18. STRANGULATION

Strangulation is a form of asphyxia caused by constriction of the neck by a ligature or by the hands, compressing the air passages, blood vessels, and nerves of the neck from the outside, resulting in obstruction to the circulation of blood to and from the brain and closure of the airway. Types include: ligature strangulation, throttling (manual strangulation), and garroting.

19. SUFFOCATION

Suffocation is a form of asphyxia caused by obstruction of the external respiratory orifices (mouth and nose) or by an atmosphere deficient in oxygen, preventing entry of air into the lungs. It includes smothering, choking, gagging, traumatic asphyxia, and environmental oxygen deprivation.

20. TYPES OF SUFFOCATION

The main types of mechanical (suffocative) asphyxia are:
  1. Smothering - closure of the external respiratory orifices
  2. Choking - obstruction of the internal airway by a foreign body
  3. Gagging - packing of the mouth to prevent breathing/calling out
  4. Traumatic asphyxia - external compression of the chest preventing respiratory movements
  5. Burking - combination of smothering and traumatic asphyxia
  6. Drowning - filling of air passages with fluid

21. SMOTHERING

Smothering is a form of suffocation (mechanical asphyxia) caused by closure or obstruction of the external respiratory orifices - the nose and mouth - either by the hand, a pillow, a cloth, or other material, preventing the entry of air into the lungs.

22. CHOKING

Choking is a form of mechanical asphyxia caused by obstruction of the internal air passages (larynx, pharynx, trachea) by a foreign body (food bolus, vomit, dentures, small objects). The obstruction prevents passage of air to the lungs from within.

23. GAGGING

Gagging is a form of suffocation in which the mouth is packed with material (cloth, tape, rags) to prevent the victim from calling for help and simultaneously obstruct breathing. When a gag is tightly applied, it can cause mechanical asphyxia by blocking the oral airway, especially if nasal breathing is also impaired.

24. TRAUMATIC ASPHYXIA (Compression Asphyxia)

Traumatic asphyxia (also called compression asphyxia) is a form of mechanical asphyxia caused by external compression of the chest wall and/or abdomen that prevents the respiratory movements of the thorax, thereby stopping the expansion of the lungs. It occurs in crush injuries (e.g., crowd crushes, building collapses, vehicle accidents). It is characterized by intense cyanosis, congestion, and petechial hemorrhages above the level of compression.

25. BURKING

Burking is a method of homicide combining smothering and traumatic asphyxia simultaneously - one person sits or presses on the victim's chest (preventing respiration by compression), while another covers the mouth and nose (smothering). Named after William Burke, who used this method in Edinburgh (1828) with his partner William Hare. The method leaves few external marks, making detection difficult.

26. GARROTING (Garroting)

Garroting is a method of homicidal ligature strangulation in which a cord, wire, or rigid instrument is placed around the victim's neck from behind and twisted or tightened, either by hand or by means of a stick (tourniquet fashion), compressing the air passages and blood vessels of the neck and causing death by asphyxia. It is also used as a method of judicial execution in some countries.

27. MUGGING

Mugging (also called arm-lock strangulation or choke hold) is a method of manual strangulation in which the assailant applies pressure to the neck of the victim using the forearm (or elbow crook) from behind, compressing the carotid arteries and/or airway. Death results from cerebral anemia or asphyxia due to compression of the neck structures.

28. THROTTLING (Manual Strangulation)

Throttling is a form of homicidal asphyxia in which the neck is compressed by the hands (one or both) applied directly around the throat, compressing the larynx, trachea, carotid arteries, and jugular veins, causing asphyxia and cerebral anemia. Characteristic findings include fingernail marks and bruises on the neck.

29. CAFE CORONARY (Cafe Coronary Syndrome)

Cafe coronary is sudden death caused by a large bolus of food (typically poorly chewed meat) becoming lodged in the laryngopharynx or larynx, causing acute airway obstruction (choking). It occurs most often in intoxicated individuals or those with impaired swallowing reflexes, typically while eating in a restaurant - hence the name, because the sudden collapse mimics a cardiac (coronary) event. It is a form of internal choking asphyxia.

30. CRECHE CORONARY (Overlying / Cot Death variant)

Creche coronary (also called "overlying") refers to the accidental suffocation of an infant by an adult lying on top of the child during sleep - typically in cases of co-sleeping - compressing the infant's chest and/or face and causing asphyxia. It is associated with intoxicated or deeply sleeping caregivers and is a recognized cause of sudden infant death.

31. DROWNING

Drowning is a form of asphyxia caused by the prevention of entry of air into the lungs due to the air passages being filled with fluid (water, mud, etc.). Death results from hypoxia caused by submersion or immersion in a liquid medium. In "wet drowning," fluid enters the lungs; in "dry drowning," reflex laryngospasm prevents water entry but still causes fatal asphyxia. Drowning can be accidental, suicidal, or homicidal.
