There are two types of anatomy: gross, or macroscopic, and microscopic. Gross anatomy deals with things that can be viewed by the unaided eye. Microscopic anatomy is the study of structures on the cellular level. There are, in turn, 3 fields of study within the topic of gross anatomy. Human anatomy – scientific study of the morphology of the adult human. It is subdivided into gross anatomy and microscopic anatomy. Gross anatomy (also called topographical anatomy, regional anatomy, or anthropology) 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, and includes histology (the study of the organization of tissues), and cytology (the study of cells).
