Suffocation,

Q. 1

Choking

Throttling

Q. 1

Which of the following is not a cause of death due to suffocation?

 A

Choking

 B

Gagging

 C

Smothering

 D

Throttling

Ans. D

Explanation:

Throttling involves compression of neck by human hands, and is a form of strangulation (and not suffocation).

Death from throttling occurs due to occlusion of carotid arteries. Occlusion of airways plays a minor role.

Q. 2

Which among the following is the abductor of vocal cord, paralysis of which could lead to suffocation?

 A

Posterior cricoarytenoid

 B

Cricothyroid

 C

Lateral cricoaretynoid

 D

Interarytenoid

Q. 2

Which among the following is the abductor of vocal cord, paralysis of which could lead to suffocation?

 A

Posterior cricoarytenoid

 B

Cricothyroid

 C

Lateral cricoaretynoid

 D

Interarytenoid

Ans. A

Explanation:

Posterior cricoarytenoid is the sole abductor of vocal cords and bilateral paralysis may lead to the adduction of vocal cords and suffocation. 

The posterior cricoarytenoid muscle causes the muscular process of the arytenoid to be pulled posteriorly and toward the opposite arytenoid. The vocal process, in turn, is pulled laterally, causing the abduction of the vocal cord.


Q. 3

Which of the following is not a cause of death due to suffocation:

 A

Choking

 B

Gagging

 C

Smothering

 D

Throttling

Q. 3

 A

Choking

 B

Gagging

 C

Smothering

 D

Throttling

Ans. D

Explanation:

D i.e. Throttling

Throttling or manual strangulation causes death due to occlusion of carotid arteries. Occlusion of airway (i.e, suffocation) plays only minor roleQ.

Fracture of the bone shown in the picture below results from all except ? 

 A

Throttling.

 B

Hanging.

 C

Choking.

 D

Ligature strangulation.

Ans. C

Explanation:

Ans:C.)Choking

The image shown is of a Hyoid bone fracture.

  • Hyoid bone fracture is most commonly seen in Strangulation(Manual or Ligature) and in Hanging.
  • “Strangulation” and “Choking” are not the same thing. 
    • Choking is when air flow is blocked by food or a foreign object in the trachea – something that can be addressed by the Heimlich maneuver.
    • Strangulation, by contrast, is defined by reduced air flow and/or blood flow to or from the brain via the intentional external compression of blood vessels or the airway in the neck. Notably, however, many victims of strangulation refer to the assault as “choking”.
    • Manual strangulationis the most common method of strangulation, although ligatures are sometimes used.
  •  In smothering, choking, gagging, there is no fracture of hyoid bone, because in these throat (neck) is not touched.

Smothering and Traumatic asphyxia.

 B

Choking and drowning.

 C

Gagging only.

 D

Traumatic asphyxia only.

Ans. A

Explanation:

Ans:A.)Smothering and Traumatic asphyxia.

The method shown in the picture represents burking.

Burking consist of smothering & traumatic asphyxia.

  • The term ‘Burking’ is derived from notorious criminal ‘Burke’, who with his accomplice ‘Hare’, killed old people by a combination of smothering and traumatic asphyxia, and sold the bodies to the medical school in Edinburgh.
  • They would follow and kill intoxicated individuals by one of them holding a hand over the victim’s nose and mouth, while the other would sit on the victim’s chest until he or she died of asphyxia.
  • In smothering, death is due to mechanical occlusion of mouth or nose, for instance by pressing a pillow or any soft material over the mouth and nose, or by manually closing these orifices.
  • In traumatic asphyxia, death results from pressure fixation of the chest and/or abdomen. Because of pressure on the chest, the victim is unable to breathe and dies of asphyxia.(Asphyxia is best described as an interference with respiration due to any cause – mechanical, environmental or toxic.)
