Gross anatomy (or macroscopic anatomy) is the study of structures of the human body that are observable with the naked eye or without the use of a microscope. Microscopic anatomy, which is usually either histology or cytology, is the study of tissues or cells which requires the use of a microscope to make out features/structures. The word gross in the term gross anatomy is used to indicate that which is large and not that which someone might find repulsive or disgusting.
