01 / Geometry
See around, not just through.
The 3D subset keeps the source positions of 6 separate structures. Rotate the arm, hide a layer, or isolate a muscle to inspect its shape.
Upper limb · Study 03
Inside the forearm.
Start with radius and ulna, then reveal the four available muscle parts. Rotate the model or open a structure for a closer look.
Atlas noteA partial, right-sided study—not a complete dissection. Most forearm muscles, hand, membrane, nerves and vessels are not modeled. Anatomical review is still required.

02 / Explore
Follow the arm to the elbow.
Continue into the elbow study for a close-up of three bones and ten muscle parts, with layers you can hide and individual structures you can select.

Shape is not photorealism.
This is a reduced-resolution model, not a complete dissection. Skin, vessels, nerves and most neighboring muscles are omitted. Colors and shading are illustrative; there are no realistic muscle-fiber textures. Anatomical review is still required.
Explore the study
From two bones to individual structures
Use the Radius and Ulna buttons to compare the bones without muscle overlap. About in the selected structure’s card opens a short source-linked description. Front and Back change your viewpoint; they do not move the bones relative to one another.
Reveal the available muscles
Enable Muscles & parts to display brachioradialis, anconeus and both modeled heads of pronator teres. Isolate shows only your selected structure. Show context restores all six structures and fits the whole subset into view.
What is missing?
This subset does not include most forearm muscles, the hand, interosseous membrane, ligaments, cartilage, nerves or vessels. Proximal muscle ends can extend beyond the displayed bones: the humerus and other neighboring structures are not loaded here. Open the elbow study for the wider upper-arm context.
The source coordinates are retained. Model colors are illustrative; this viewer does not simulate pronation or supination.
