Term | Definition |
---|---|
anatomy | "to cut up" - translated to mean the study of structure based largely on dissection |
physiology | "the study of nature" - translated to mean the study of how things function |
biology | "the study of life" - including many sciences like zoology and botany |
microscopic anatomy | includes" histology, cytology, and ultrastructure the study of anatomical systems too small to see with the human eye |
histology | studies the 4 basic tissue types using a standard light microscope |
cytology | studies of cellular structures using a standard light microscope and EM |
ultrastructure | studies subcellular structures and macromolecules using an electron microscope |
gross anatomy | includes: developmental anatomy, surface anatomy, the regional approach and systematic approach study of anatomical structures that you can see with the naked eye |
developmental anatomy | the study of development from gametogenesis to senescence |
surface anatomy | anatomy that you can see/touch on a patient example: a bump, scrape, etc. |
metabolism | sum total of catabolic and anabolic reactions |
homeostasis | maintenance of a stable internal environment |
five major characteristics of humans: | 1: a large, well developed brain weighing approx. 3 lbs., 2: bipedal locomotion w/ sigmoidal curvature of the spine, 3: stereoscopic vision directed forwards for depth perception, 4: opposable thumbs with a saddle joint, 5: well developed vocal structures |
