One of the large, detailed illustrations in Andreas Vesalius's De humani corporis fabrica 16th century,245x245px<unk>  (Greek<unk> , 'dissection') is the branch of biology concerned with the study of the structure of organisms and their parts.<unk>  is a branch of natural science which deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times.<unk>  is inherently tied to developmental biology, embryology, comparative<unk> , evolutionary biology, and phylogeny, as these are the processes by which<unk>  is generated, both over immediate and long-term timescales.<unk>  and physiology, which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human<unk>  is one of the essential basic sciences that are applied in medicine. The discipline of<unk>  is divided into macroscopic and microscopic. Macroscopic<unk> , or gross<unk> , is the examination of an animal's body parts using unaided eyesight. Gross<unk>  also includes the branch of superficial<unk> . Microscopic<unk>  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<unk>  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 (corpses) to 20th century medical imaging techniques including X-ray, ultrasound, and magnetic resonance imaging.
