ἀνατομία, "dissection", from ἀνά, "up", and τέμνειν, "cut") is primarily the scientific study of the morphology of the human body.
In some of its facets human anatomy is closely related to embryology, comparative anatomy and comparative embryology,[1] through common roots in evolution; for example, much of the human body maintains the ancient segmental pattern that is present in all vertebrates with basic units being repeated, which is particularly obvious in the vertebral column and in the ribcage, and can be traced from very early embryos.
The history of anatomy has been characterized, over a long period of time, by a continually developing understanding of the functions of organs and structures in the body.
The study of microscopic anatomy (or histology) can be aided by practical experience examining histological preparations (or slides) under a microscope; and in addition, medical and dental students generally also learn anatomy with practical experience of dissection and inspection of cadavers (dead human bodies).
Basic concepts of how muscles and bones function and deform with movement is key to drawing, painting or animating a human figure.
