An autopsy, necropsy, or autopsy is the dissection and examination of a corpse to determine the cause of death or to learn about the development of a disease. Since the Middle Ages, autopsy has made a great contribution to the development of science. In addition to revealing the causes of death, autopsy is key to educating medical students, understanding new diseases, and advancing medical science. An autopsy is a surgical procedure that consists of a thorough examination of a corpse by dissection to determine the cause, mode and manner of death or to assess any disease or injury that may be present, which is done for research or educational purposes. (The term "necropsy" is mostly reserved for non-human animals). An autopsy is usually performed by a specialist called a pathologist. In most cases, a medical investigator or coroner can determine the cause of death, and only a small proportion of deaths require an autopsy.
Autopsies are performed for legal or medical purposes. An autopsy can be performed when any of the following information is desired:
Determining whether death was natural or unnatural
Source and degree of injury to the corpse
The mode of death must be determined
Time of death
Determining the identity of the deceased
Retention of relevant organs
In the case of infants, determining whether a child was born alive and whether he or she could have remained alive. unknown or uncertain deaths, or for research purposes. Autopsies can be further classified into cases where an external examination is sufficient and those in which the body is dissected and an internal examination performed. In some cases, the permission of the next of kin may be required for an internal autopsy. When the internal autopsy is completed, the body is reconstituted by reuniting.
The main objectives of the autopsy are to determine the cause of death, the modality of death, the manner of death, the health condition of the person before he died and whether any medical diagnosis and treatment before death was appropriate. In most Western countries, the number of autopsies performed in hospitals has been declining every year since 1955. Critics, including
