It is an old science, having its beginnings in prehistoric times.Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny,as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy 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 anatomy is one of the essential basic sciences that are applied in medicine
