History of pathology
The history of pathology can be traced to the earliest application of the scientific method to the field of medicine, a development which occurred in the Middle East during the Islamic Golden Age and in Western Europe during the Italian Renaissance. The can be traced to the earliest application of the Scientific method to the field of Medicine, a development which occurred in the Middle East during Scientific method refers to bodies of Techniques for investigating phenomena 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 Middle East is a Subcontinent with no clear boundaries often used as a synonym to Near East, in opposition to Far East. Western Europe at its most general meaning means 'all the countries in the West of Europe ' The Italian Renaissance began the opening phase of the Renaissance, a period of great cultural change and achievement in Europe that spanned the period from the end of the 14th The first physician known to have made postmortem dissections was the Arabian physician Avenzoar (1091–1161). An autopsy, also known as a post-mortem examination, necropsy, or obduction, is a Medical procedure that consists of a thorough Examination 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 The araB gene Promoter is a bacterial promoter activated by e L-arabinose binding Abū Merwān ’Abdal-Malik ibn Zuhr ( أبو مروان عبد الملك بن زهر) (also known as Ibn Zuhr, Avenzoar, Abumeron or Ibn-Zohr Rudolf Virchow (1821-1902) is generally recognized to be the father of microscopic pathology. Rudolf Ludwig Karl Virchow ( 13 October 1821 &ndash 5 September 1902) was a German doctor, anthropologist, public health Most early pathologists were also practicing physicians or surgeons.

General pathology
General pathology, also called investigative pathology, experimental pathology or theoretical pathology, is a broad and complex scientific field which seeks to understand the mechanisms of injury to cells and tissues, as well as the body's means of responding to and repairing injury. Pathology; please do not remove --> also called, or, is a broad and complex scientific field Science (from the Latin scientia, meaning " Knowledge " or "knowing" is the effort to discover, and increase human understanding The cell is the structural and functional unit of all known living Organisms It is the smallest unit of an organism that is classified as living and is often called Tissue is a cellular organizational level intermediate between cells and a complete organism Areas of study include cellular adaptation to injury, necrosis, inflammation, wound healing and neoplasia. Necrosis (in Greek Νεκρός = "dead" is the name given to unnatural Death of cells and living tissue. Inflammation ( Latin, inflamatio, to set on fire is the complex biological response of vascular tissues to harmful stimuli such as Pathogens Wound healing, or wound repair, is the body's natural process of regenerating dermal and epidermal tissue.

Pathology as a medical specialty
Pathologists are physicians who diagnose and characterize disease in living patients by examining biopsies or bodily fluid.

Cancer (medical term Malignant Neoplasm) is a class of Diseases in which a group of cells display uncontrolled Pathologists may also conduct autopsies to investigate causes of death. An autopsy, also known as a post-mortem examination, necropsy, or obduction, is a Medical procedure that consists of a thorough Examination Pathology is a core discipline of medical school and many pathologists are also teachers. Medical education A medical school or faculty of medicine is a Tertiary educational institution—or part of such an institution—that teaches Medicine As managers of medical laboratories, pathologists play an important role in the development of Laboratory information systems. A medical laboratory or clinical laboratory is a Laboratory where tests are done on clinical specimens in order to get information about the Health A lab information system (LIS is a class of Software which handles receiving processing and storing information generated by Medical laboratory processes Although the medical practice of pathology grew out the tradition of investigative pathology, most modern pathologists do not perform original research.

Pathology is a unique medical specialty in that pathologists typically do not see patients directly, but rather serve as consultants to other physicians (often referred to as "clinicians" within the pathology community). A patient is any person who receives medical attention care or treatment. To be licensed, candidates must complete medical training, an approved residency program and be certified by an appropriate body. In the US, certification is by the College of American Pathologists. The College of American Pathologists (CAP is a medical society serving more than 16000 physician members and the laboratory community throughout the world The organization of subspecialties within pathology vary between nations but usually include anatomical pathology and clinical pathology.

Anatomical pathology
Anatomical pathology (Commonwealth) or Anatomic pathology (U. Pathology; please do not remove --> ( S. ) is a medical specialty that is concerned with the diagnosis of disease based on the gross, microscopic, and molecular examination of organs, tissues, and whole bodies (autopsy). Gross examination or "grossing" is the process by which Pathology specimens are inspected with the naked eye to obtain diagnostic information while being Histopathology (from the Greek histos (tissue and pathos (suffering refers to the microscopic examination of tissue in order to study the manifestations Molecular pathology is an emerging discipline within Pathology which is focused in the study and diagnosis of disease through the examination of molecules within organs tissues or bodily In Biology, an organ ( Latin: organum, "instrument tool" from Greek όργανον - organon "organ instrument Tissue is a cellular organizational level intermediate between cells and a complete organism An autopsy, also known as a post-mortem examination, necropsy, or obduction, is a Medical procedure that consists of a thorough Examination The anatomical pathologist reports to doctors; he (she) does not usually see patients.
Anatomical pathology is itself divided in subspecialties, the main ones being surgical pathology, cytopathology and forensic pathology. Surgical pathology is the most significant and time-consuming area of practice for most anatomical pathologists. Cytopathology (from Greek grc κύτος kytos, "a hollow" grc πάθος pathos, "fate harm" and grc -λογία -logia Forensic pathology is a branch of Pathology concerned with determining the Cause of death by examination of a cadaver To be licensed to practice anatomical pathology, one has to complete medical school, an approved residency program and be certified. In most countries only persons with a medical license bestowed either by a specified government-approved Professional association or a Government agency are authorized Medical education A medical school or faculty of medicine is a Tertiary educational institution—or part of such an institution—that teaches Medicine Residency is a stage of graduate medical training. A resident physician or resident is a person who has received a Medical degree ( MD In the U. S. , the American board of Pathology certifies pathologists.

Plant pathology
Phytopathology (plant pathology) is the scientific study of plant diseases caused by pathogens (infectious diseases) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are insects, mites, vertebrate or other pests that affect plant health by consumption of plant tissues. Plant pathology also involves the study of the identification, etiology, disease cycle, economic impact, epidemiology, how plant diseases affect humans and animals, pathosystem genetics and management of plant diseases.
