See also:ANATOMY (Gr. avaroyil, from See also:ava-silo c', to cut up) , literally See also:dissection or cutting asunder, a See also:term always used to denote the study of the structure of living things; thus there is See also:animal See also:anatomy (zootomy) and See also:vegetable anatomy (phytotomy) . Animal anatomy may include the study of the structure of different animals, when it is called See also:comparative anatomy or animal See also:morphology, or it may be limited to one animal only, in which See also:case it is spoken of as See also:special anatomy . From a utilitarian point of view the study of See also:Man is the most important See also:division of special anatomy, and this human anatomy may be approached from different points of view . From that of the medical man it consists of a knowledge of the exact See also:form, position, See also:size and relationship of the various structures of the human See also:body in See also:health, and to this study the term descriptive or topographical human anatomy is given, though it is often, less happily, spoken of as Anthropotomy . An accurate knowledge of all the details of the human body takes years of patient observation to gain and is possessed by only a few . So intricate is man's body that only a small number of professional human anatomists are See also:complete masters of all its details, and most of them specialize on certain parts, such as the See also:brain, viscera, &c.; contenting themselves with a See also:good working knowledge of the See also:rest . Topographical anatomy must be learned by each See also:person for himself by the repeated dissection and inspection of the dead human body . It is no more a See also:science than a See also:pilot's knowledge is, and, like that knowledge, must be exact and available in moments of emergency . From the morphological point of view, however, human anatomy is a scientific and fascinating study, having for its See also:object the See also:discovery of the causes which have brought about the existing structure of Man, and needing a knowledge of the allied sciences of See also:embryology or ontogeny, phylogeny and See also:histology . Pathological or morbid anatomy is the study of diseased See also:organs, while sections of normal anatomy, applied to various purposes, receive special names such as medical, surgical, gynaecological, See also:artistic and superficial anatomy . The comparison of the anatomy of different races of mankind is See also:part of the science of See also:physical See also:anthropology or anthropological anatomy . In the See also:present edition of this See also:work the subject of anatomy is treated systematically rather than topographically . Each anatomical See also:article contains first a description of the structures of an See also:organ or See also:system (such as nerves, See also:arteries, See also:heart, &c.), as it is found in Man; and this is followed by an See also:account of the development or embryology and comparative anatomy or morphology, as far as vertebrate animals are concerned; but only those parts of the See also:lower animals which are of See also:interest in explaining Man's structure are here dealt with . The articles have a twofold purpose; first, to give enough details of man's structure to make the articles on See also:physiology, See also:surgery, See also:medicine and See also:pathology intelligible; and, secondly, to give the non-See also:expert inquirer, or the worker in some other See also:branch of science, the See also:chief theories on which the See also:modern scientific groundwork of anatomy is built . The following See also:separate anatomical articles will be found under their own headings: Alimentary See also:canal . Arteries . Brain . Coelom and serous membranes . Connective tissues . See also:Diaphragm . Ductless glands . See also:Ear . See also:Epithelial, endothelial and glandular tissues . See also:Eye . Heart . See also:Joints . See also:Liver . Lymphatic system . Mammary gland . Mouth and salivary glands . See also:Muscular system . |
