What Are Some Key Differences Between Veterinary Medicine and Human Anatomy When it Comes to Postmortem Examinations?

Step Action Novel Insight Risk Factors
1 In human anatomy, postmortem examinations are called autopsies, while in veterinary medicine, they are called necropsies. The terminology used in postmortem examinations differs between human and veterinary medicine. None
2 In human autopsies, the focus is on determining the cause of death and disease diagnosis, while in animal necropsies, the focus is on disease diagnosis and determining the cause of death is secondary. The primary focus of postmortem examinations differs between human and veterinary medicine. Misdiagnosis of the cause of death in animals due to the secondary focus on determining the cause of death.
3 In human autopsies, gross examination and histopathology are the most commonly used techniques, while in animal necropsies, tissue sampling, microbiology culture, and radiography imaging are also commonly used. The techniques used in postmortem examinations differ between human and veterinary medicine. Misdiagnosis of the cause of death in animals due to the reliance on a single technique.
4 In human autopsies, toxicology testing is commonly used to determine if drugs or toxins played a role in the cause of death, while in animal necropsies, toxicology testing is less commonly used. The use of toxicology testing differs between human and veterinary medicine. Misdiagnosis of the cause of death in animals due to the lack of toxicology testing.
5 In human autopsies, tissue preservation is important for future research and legal purposes, while in animal necropsies, tissue preservation is less commonly used. The importance of tissue preservation differs between human and veterinary medicine. Loss of valuable research or legal evidence in animals due to the lack of tissue preservation.
6 In forensic pathology, postmortem examinations are used to determine the cause of death in criminal cases, while in animal pathology, postmortem examinations are used to improve animal health and prevent disease outbreaks. The purpose of postmortem examinations differs between forensic and animal pathology. None

Common Mistakes And Misconceptions

Mistake/Misconception Correct Viewpoint
Autopsy and necropsy are the same thing. Autopsy is performed on humans while necropsy is performed on animals.
The purpose of autopsy and necropsy is to determine the cause of death. While determining the cause of death is a common reason for performing an autopsy or necropsy, they can also be used for research purposes, legal investigations, and medical education.
Only forensic pathologists perform autopsies and necropsies. While forensic pathologists do perform these procedures in cases involving criminal investigations or suspicious deaths, other medical professionals such as coroners, medical examiners, and veterinarians may also conduct them depending on their jurisdiction or specialty area.
Autopsies and necropsies are always invasive procedures that involve cutting open the body. While some autopsies/necropsies may require incisions to be made in order to examine internal organs/tissues, non-invasive methods such as imaging techniques (e.g., X-rays) can also be used to gather information about the body’s condition before/after death.
Performing an autopsy/necropsy means disrespecting/devaluing the deceased individual/animal. On the contrary, performing an autopsy/necropsy can provide valuable information that helps improve our understanding of diseases/disorders affecting humans/animals which could lead to better treatments/preventative measures being developed in future.
