What is the technical name for the study of the structure of the human body that can be seen with the naked eye?

Anatomy is the study of the structure of the human body and its parts that can be seen with the naked eye, while physiology is the study of how those structures function. Cosmetologists study basic anatomy and physiology of the skin, hair, nails, and underlying structures (such as muscles, bones, and circulation of the head, face, neck, and hands) so they can perform services safely and recognize conditions. Distinguishing anatomy (structure) from physiology (function) is a basic but commonly tested definition.
