Tags: autopsy stomach trauma. Latest Highest Rated. The word "autopsy" comes from the Greek words "auto" and "opsis", and it literally means "to see for oneself".
An autopsy is performed to determine the cause, manner and mechanism of death. To understand the human anatomy better, and to improve their skills, the artists Leonardo da Vinci and Michelangelo each performed autopsies.
The autopsy really became significant inwhen Giovanni Morganni published his great work On the Seats and Causes of Diseases as Investigated by Anatomy. This work contained descriptions of autopsies. A medical or clinical autopsy is performed to determine the medical cause of death or for research purposes. A legal or forensic autopsy is performed when the cause of death is a possible criminal manner. Organs, tissues, stem cells and blood and platelets may be donated.
Most people can be donors HIV positive, cancer active or systemic infection cannot donate. Donated organs must be transplanted within hours and cannot be stored.
Tissues, stem cells, blood and platelets may be stored for later use. These opinions may be influenced by religion, fear, cultural beliefs and taboos. A forensic autopsy will be performed by a Medical Examiner M. A coroner does not perform an autopsy. A funeral director or mortician does not perform an autopsy. The M. The body bag is unsealed and opened. The body is photographed in the body bag. Description of the clothing is recorded. Evidence is collected from the clothing and the body.
If it is a homicide investigation, the hands will have been bagged at the scene. UV radiation is used to enhance any secretions that should be collected. X-rays are taken. The body is removed from the bag and undressed in preparation for the external examination.An autopsy is performed by a physician trained in pathology.
Most autopsies advance medical knowledge and provide evidence for legal action. Medically, autopsies determine the exact cause and circumstances of deathdiscover the pathway of a disease, and provide valuable information to be used in the care of the living. When foul play is suspected, a government coroner or medical examiner performs autopsies for legal use. This branch of medical study is called forensic medicine.
Forensic specialists investigate deaths resulting from violence or occurring under suspicious circumstances.
Benefits of research from autopsies include the production of new medical information on diseases such as toxic shock syndromeacquired immunodeficiency syndrome AIDS. Organ donation, which can potentially save the lives of other patients, is also another benefit of autopsies. A person infected with HIV gradually loses immune function, becoming less able to resist aliments and cancers, resulting in eventual death. Computed tomography scan CT scan — The technique used in diagnostic studies of internal bodily structures in the detection of tumors or brain aneurysms.
This diagnostic test consists of a computer analysis of a series of cross-sectional scans made along a single axis of a bodily structure or tissue that is used to construct a three-dimensional image of that structure. Creutzfeld-Jakob disease — A rare, often fatal disease of the brain, characterized by gradual dementia and loss of muscle control that occurs most often in middle age and is caused by a slow virus.
Hepatitis — Inflammation of the liver, caused by infectious or toxic agents and characterized by jaundice, fever, liver enlargement, and abdominal pain. Magnetic resonance imaging MRI — A diagnostic tool that utilizes nuclear magnetic energy in the production of images of specific atoms and molecular structures in solids, especially human cells, tissues, and organs.
When performed for medical reasons, autopsies require formal permission from family members or the legal guardian. Autopsies required for legal reasons when foul play is suspected do not need the consent of next of kin. During the autopsy, very concise notes and documentation must be made for both medical and legal reasons. Some religious groups prohibit autopsies. An autopsy can be described as the examination of a deceased human body with a detailed exam of the person's remains.
This procedure dates back to the Roman era when few human dissections were performed; autopsies were utilized, however, to determine the cause of death in criminal cases. At the beginning of the procedure the exterior body is examined and then the internal organs are removed and studied.
Some pathologists argue that more autopsies are performed than necessary. However, recent studies show that autopsies can detect major findings about a person's condition that were not suspected when the person was alive. And the growing awareness of the influence of genetic factors in disease has also emphasized the importance of autopsies.
Despite the usefulness of autopsies, fewer autopsies have been performed in the United States during the past years. A possible reason for this decline is concern about malpractice suits on the part of the treating physician. Other possible reasons are that hospitals are performing fewer autopsies because of the expense or because modern technology, such as CT scans and magnetic resonance imaging, can often provide sufficient diagnostic information. Nonetheless, federal regulators and pathology groups have begun to establish new guidelines designed to increase the number and quality of autopsies being performed.
Many experts are concerned that if the number of autopsies increases, hospitals may be forced to charge families a fee for the procedure as autopies are not normally covered by insurance companies or Medicare. Yet, according to several pathologists, the benefit of the procedure for families and doctors does justify the cost. In medical autopsies, physicians remain cautious to examine only as much of the body as permitted according to the wishes of the family.
It is important to note that autopsies can also provide peace of mind for the bereaved family in certain situations. If a medical autopsy is being performed, written permission is secured from the family of the deceased?? Once the autopsy has been completed, the body is prepared for final arrangements according to the family's wishes??Toxicology is traditionally defined as "the science of poisons.
These adverse effects can take many forms, ranging from immediate death to subtle changes not appreciated until months or years later.
They may occur at various levels within the body, such as an organ, a type of cell, or a specific biochemical. Our understanding of how toxic agents damage the body has progressed along with medical knowledge.

We now know that various observable changes in anatomic or bodily functions actually result from previously unrecognized changes in specific biochemicals in the body.
The study of toxicology may appear to focus only on poisonings or disasters, but some toxic chemicals can have positive effects. Animal venoms, whether from bees, wasps, snakes, or Gila monsters, are composed of hundreds of chemicals that are being studied as treatments for human diseases.
For example, exantide, a drug derived from Gila monster saliva, has been approved for use in Type 2 diabetes. Captopril, which is used to treat hypertension and heart failure, was developed from studies on the chemical bradykinin-potentiating factor BPF in the venom of a South American snake Bothrops jararaca.
Melitten, which comes from honeybee venom, is being investigated for its anticancer and antifungal properties. Figure 1. Written records indicate that hemlock, opium, arrow poisons, and certain metals were used to poison enemies or for state executions. With time, people began to make the connection between exposure to a specific substance and illness or death.
Certain fundamental toxicology concepts began to take shape. Noteworthy studies include those by Paracelsus in the 16 th century and Orfila in the 19 th century. Determined that specific chemicals were actually responsible for the toxicity of a plant or animal poison.
Documented that the body's response to those chemicals depended on the dose received. Studies revealed that small doses of a substance might be harmless or beneficial, whereas larger doses could be toxic. The right dose differentiates a poison and a remedy. Orfila was the first to describe a systematic correlation between the chemical and biological properties of poisons of the time. Orfila demonstrated the effects of poisons on specific organs by analyzing autopsy materials for poisons and tissue damage associated with them.
Marked by great advancements in the level of understanding of toxicology. DNA and various biochemicals that maintain body functions have been discovered. Our level of knowledge of toxic effects on organs and cells has expanded to the molecular level. Virtually all toxic effects are recognized as being caused by changes in specific cellular molecules and biochemicals.
Xenobiotic is the general term used for a foreign substance taken into the body. The word is derived from the Greek term xenowhich means foreigner.Copy embed code:.

PowerPoint Presentation: Clinical toxicology deals with diseases caused by or associated with toxic substances PowerPoint Presentation: Environmental toxicology focuses on the hazards of chemical pollutants in the environment on biological organisms.
Ecotoxicology is a specialized area within environmental toxicology that focuses more specifically on the impacts of toxic substances on population dynamics in an ecosystem. The transport, fate, and interactions of chemicals in the environment constitute a critical component of both environmental toxicology and ecotoxicology. Poison is a quantitative concept, almost any substance being harmful at some doses but, at the same time, being without harmful effect at some lower dose.
Between these two limits there is a range of possible effects, from subtle long-term chronic toxicity to immediate lethality. Toxicant is any chemical, of natural or synthetic origin, capable of causing a harmful effect to a living organism. Toxin is a toxicant produced by a living organism and is not used as a synonym for toxicant all toxins are toxicants, but not all toxicants are toxins Modes of Toxic Action: Modes of Toxic Action Includes the consideration of all events leading to toxicity in vivo: uptake, distribution, metabolism, mode of action, and excretion.
The term mechanism of toxic action is now more generally used to describe an important molecular event leading to toxicitysuch as the inhibition of acetylcholinesterase in the toxicity of organophosphorus and carbamate insecticides.

Autopsies are requested to find out the cause of the death. Usually to find results from a homicide or suicide. The study of Autopsy is called Pathology. Autopsies are usually performed within 24 hrs and take about hrs. Medical Examiners then test the body's urine, blood, gel from the eye, and bile from the gallbladder for drugs or infections. The organs are removed and weighed. Step 6 Autopsy Step 2 Total years They remove and dissect the abdominal organs.

This document pictures the scene of death for the prosector. Often ML postmortem has to be conducted in places where none or minimal facilities are available.
On-site autopsies are common after exhumation for grossly decomposed dead bodies. All medico-legal autopsies are complete autopsies. Hence a thorough external and internal examination of all organs is carried out in all cases.
