Human anatomy deals with the study of the human body, its structures, and how these structures specifically function. Microscopic anatomy on the other hand deals with structures found within the body that cannot be seen by the naked eye but can be viewed with the use of the microscopic. Microscopic anatomy deals with the study of the smallest structures of the cells, tissues, and organs of the body.
