Anatomy is the branch of biology concerned with the study of the structure of organisms and their parts . Anatomy is inherently tied to embryology , comparative anatomy , evolutionary biology , and phylogeny , as these are the processes by which anatomy is generated over immediate -LRB- embryology -RRB- and long -LRB- evolution -RRB- timescales . Human anatomy is one of the basic essential sciences of medicine .   The discipline of anatomy is divided into macroscopic and microscopic anatomy . Macroscopic anatomy , or gross anatomy , is the examination of an animal 's body parts using unaided eyesight . Gross anatomy also includes the branch of superficial anatomy . Microscopic anatomy involves the use of optical instruments in the study of the tissues of various structures , known as histology , and also in the study of cells .   The history of anatomy is characterized by a progressive understanding of the functions of the organs and structures of the human body . Methods have also improved dramatically , advancing from the examination of animals by dissection of carcasses and cadavers -LRB- corpses -RRB- to 20th century medical imaging techniques including X-ray , ultrasound , and magnetic resonance imaging .   Anatomy and physiology , which study -LRB- respectively -RRB- the structure and function of organisms and their parts , make a natural pair of related disciplines , and they are often studied together .
