The arm is a kinetic chain composed of three major bone segments (arm, forearm, hand) connected by complex joints. Understanding how muscles stretch, compress, and twist during motion is essential for creating believable, non-rigid sculptures.
The arm is comprised of three long bones: the humerus, radius, and ulna. The humerus, or upper arm bone, connects the shoulder to the elbow, while the radius and ulna form the forearm. The radius and ulna are responsible for the rotational movements of the forearm, allowing for pronation (palm facing downwards) and supination (palm facing upwards). anatomy for sculptors arm and hand in motion
This report analyzes the anatomical mechanics of the upper limb with a specific focus on the needs of the sculptor. Unlike medical anatomy, which focuses on internal function, artistic anatomy prioritizes . The arm is a kinetic chain composed of
