I've been searching for a book to do this for ages. Photographs of real people with line drawings overlaid to show, for example, where a particular muscle lies in relation to the surface of the leg; where precisely (at a vertebral level) the lungs lie within the thorax. The regions , systems and functions of the body are clearly worked through so that it becomes possible for those of us who are not planning on being surgeons (and for all I know, those that are!) to understand what you might be palpating.
