Dissection (also called anatomization) is usually the process of disassembling and observing something to determine its internal structure and as an aid to discerning the function and relationships of its components. It may refer also to some spontaneous natural process of disassembly as in aortic dissection.

In biology

Dissection is usually applied to the examination of plants and animals. The term is also used in relation to mechanisms, computer programs, written materials, etc. , as a synonym for terms such as reverse engineering or literary deconstruction. Reverse engineering (RE is the process of discovering the technological principles of a device object or system through analysis of its structure function and operation Deconstruction is a term used in Philosophy, Literary criticism, and the Social sciences, popularised through its usage by Jacques Derrida in Dissection is usually performed by students in courses of biology, botany and anatomy and in association with medical and arts studies. Foundations of modern biology There are five unifying principles Botany, plant science(s, phytology, or plant biology is a branch of Biology and is the scientific study of plant Life Anatomy (from the Greek anatomia, from ana separate apart from and temnein, to cut up cut open is a branch of Biology that is the consideration Medicine is the art and science of healing It encompasses a range of Health care practices evolved to maintain and restore Human Health by the The arts is a broad subdivision of Culture, composed of many expressive disciplines.

Vivisection refers to the dissection of a living animal, often for the purposes of physiological investigation. Physiology (from Greek grc φύσις physis, "nature origin" and grc -λογία -logia) is the study of the mechanical physical However, in modern parlance the term is often used to refer to any type of experimentation in which animals are injured, with or without actual dissection. In scientific inquiry an experiment ( Latin: Ex- periri, "to try out" is a method of investigating particular types of research questions or

Dissection is often performed as a part of determining a cause of death in autopsy (on humans) and necropsy (on animals) and is an intrinsic part of forensic medicine, such as would be practiced by a coroner. An autopsy, also known as a post-mortem examination, necropsy, or obduction, is a Medical procedure that consists of a thorough Examination An autopsy, also known as a post-mortem examination, necropsy, or obduction, is a Medical procedure that consists of a thorough Examination A coroner is an official responsible for investigating deaths particularly some of those happening under unusual circumstances and determining the cause of death

High school students stereotypically dissect frogs, rats, or fetal pigs in science class, but the trend in the U.S. is towards allowing students to opt out of dissection activities or perform dissections electronically on the computer, with programs capable of performing virtual dissections on a variety of animals. Fetal pigs are unborn pigs used in elementary as well as advanced Biology classes as objects for Dissection. The United States of America —commonly referred to as the

History

Early systematic human dissections were carried out by the Roman physicians Herophilus of Chalcedon and Erasistratus of Chios in the early part of the third century BC. Herophilos, sometimes Latinized Herophilus (335-280 BC was a Greek physician Erasistratus of Chios (304 BC- 250 BC was a Greek anatomist and royal physician under Seleucus I Nicator of Syria ^[1]Before and after this time investigators appeared to largely limit themselves to non human animals.

Later, human dissections were conducted by the Arabian physician Ibn Zuhr (Avenzoar) (1091-1161) in al-Andalus,^[2] followed by several other Arabian physicians: Saladin's physician Ibn Jumay in the 12th century, Abd-el-latif in Egypt circa 1200,^[3] and Ibn al-Nafis in Syria circa 1242. Abū Merwān ’Abdal-Malik ibn Zuhr ( أبو مروان عبد الملك بن زهر) (also known as Ibn Zuhr, Avenzoar, Abumeron or Ibn-Zohr Al-Andalus (الأندلس was the Arabic name given to those parts of the Iberian Peninsula governed by Muslims or Salahadin Ayyubi ( Arabic:صلاح الدين يوسف بن أيوب Kurdish: سه‌لاحه‌دین ئه‌یوبی Selah'edînê Eyubî; c Abd-al-latif, Abd-el-latif or Abd-ul-Latif (1162 &ndash 1231 also known as al-Baghdadi ( Arabic, عبداللطيف البغدادي This article is about the country of Egypt For a topic outline on this subject see List of basic Egypt topics.
