    Anatomy is primarily the study of body structure and the relationships among structures．It was first studied by dissection,the careful cutting apart of body structures to study their relationships．Today,a variety of imagingtechniques also contribute to the advancement of anatomical knowledge.The anatomy of the human body can be studied at various levels of structural organization,ranging from microscopic(visible only with the aid of a microscope) to macroscopic (visible without the use of a microscope)．These levels and the different methods used to study them provide the basis for the subdisciplines of anatomy,such as sectional anatomy(断层解剖学),gross anatomy(大体解剖学),systematic anatomy(系统解剖学),regional anatomy(局部解剖学),surface anatomy(表面解剖学),radiographic anatomy(X线解剖学),pathological anatomy(病理解剖学),and so forth．
