Open the PDF to the skeleton overlay pages. Do not touch clay yet. Trace the medial epicondyle of the humerus, the styloid process of the radius, and the pisiform bone of the wrist. These bony points remain fixed regardless of motion.
When the bicep contracts, it shortens, thickens, and creates a distinct peak.

The book by Anatomy For Sculptors is a specialized artist's reference that focuses on the complex movements and deformations of the upper limb. It is designed to help visual artists—including sculptors, 3D modelers, and illustrators—master the variable forms that occur during dynamic poses. Key Features and Content
The clavicle acts as a crane arm. When the arm raises, the clavicle rotates upward and backward. Open the PDF to the skeleton overlay pages
: Every significant pose is captured from several viewpoints to ensure your sculpts look correct from every side.
The wrist is not a flat hinge; it is a flexible, interlocking arch of eight small carpal bones. This arch creates a natural cup shape that transitions directly into the palm. 2. Pronation and Supination: The Great Twist These bony points remain fixed regardless of motion
The final page of the "Arm and Hand in Motion" PDF leaves the sculptor with a single mantra: Do not copy an anatomy chart. Observe how the bony landmarks (ulnar styloid, radial head, medial epicondyle) shift relative to each other as the arm moves. Capture the gesture of the limb—the tension, the relaxation, the stretch—and the muscles will follow.
Capturing the human upper limb in art is a notorious challenge for figurative artists, 3D modelers, and traditional sculptors. The complex mechanics of the shoulder, the twisting of the forearm, and the expressive flexibility of the hand require more than a surface-level understanding of anatomy.
