Question: Who played in both Cold Case and Grey's Anatomy?

Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal.  In birds this is termed "topography".  Surface anatomy deals with anatomical features that can be studied by sight, without dissection.  As such, 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. <SEP>  Introduced as a surgical intern at the fictional Seattle Grace Hospital, Karev eventually obtained the position of resident, later becoming a pediatric surgical fellow.
