==Mechanism of death== | |||
The mechanism of death in [[asphyxial death]]s seems to be an exam favourite. | |||
The short answer it is: | |||
*Brain stem hypoxia due to ischemia caused by venous obstruction in the neck.<ref>URL: [http://www.forensicmed.co.uk/pathology/mechanisms-of-death/ http://www.forensicmed.co.uk/pathology/mechanisms-of-death/]. Accessed on: 1 May 2012.</ref><ref>URL: [http://www.forensicmed.co.uk/pathology/pressure-to-the-neck/ http://www.forensicmed.co.uk/pathology/pressure-to-the-neck/]. Accessed on: 1 May 2012.</ref> | |||
The long answer is: | |||
*It depends on who one asks. Other explanations include "cardiac inhibition secondary to nerve stimulation" and "respiratory asphyxia".<ref name=pmid20456578>{{Cite journal | last1 = Clément | first1 = R. | last2 = Redpath | first2 = M. | last3 = Sauvageau | first3 = A. | title = Mechanism of death in hanging: a historical review of the evolution of pathophysiological hypotheses. | journal = J Forensic Sci | volume = 55 | issue = 5 | pages = 1268-71 | month = Sep | year = 2010 | doi = 10.1111/j.1556-4029.2010.01435.x | PMID = 20456578 }}</ref> | |||
