This drawing shows bones and muscles in a mammal’s shoulder. The bones are gray and look solid, with a ball-shaped joint. Muscles wrap around them in tight, wavy lines—some thick, some thin. The shading is all done with pencil strokes, no color. The artist focused on how muscles connect to bones. The lines look hand-drawn, almost like a sketch for a science book. Look up cross-hatching to see how artists use layers of lines to create depth.
