Human anatomy, which, with human physiology and biochemistry, is a complementary basic medical science, is primarily the scientific study of the morphology of the human body. Anatomy is subdivided into gross anatomy and microscopic anatomy. Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision. Microscopic anatomy is the study of minute anatomical structures assisted with microscopes, which includes histology (the study of the organization of tissues), and cytology (the study of cells). Anatomy, physiology (the study of function) and biochemistry (the study of the chemistry of living structures) are complementary basic medical sciences when applied to the human body. As such, these subjects are usually taught together (or in tandem) to students in the medical sciences.— Excerpted from Human anatomy on Wikipedia, the free encyclopedia.
