This drawing shows the muscles in a monkey’s arm, laid out flat like a map. You can see tendons, veins, and the way the skin folds over the hand. A needle is stuck in the forearm, marking a spot. The artist focused on how muscles twist and connect under the skin. This kind of detailed drawing was often used for studying anatomy. Next, look up cross-hatching to see how artists create depth with lines.
