Surface anatomy (also known as superficial anatomy and visual anatomy) is the study of the external features of the body. It deals with anatomical features that can be studied by sight, without dissection. It is a branch of gross anatomy, along with endoscopic and radiological anatomy. Surface anatomy is a descriptive science. In particular, in the case of human surface anatomy, these are the form and proportions of the human body and the surface landmarks which correspond to deeper structures hidden from view, both in static pose and in motion.
