Bones of the Arm

This 3D model showcases the key bones of the upper limb: the humerus, radius, ulna, and the bones of the hand, including the carpals, metacarpals, and phalanges.

• Humerus: The long bone of the upper arm, connecting the shoulder to the elbow, featuring the head, greater tubercle, and epicondyles.

• Radius and Ulna: The parallel bones of the forearm; the radius is lateral, and the ulna is medial, articulating with the humerus at the elbow and with the wrist.

• Hand Bones: Including the 8 carpal bones (forming the wrist), 5 metacarpals (forming the palm), and 14 phalanges (forming the fingers and thumb).

This model allows for interactive exploration, highlighting key anatomical landmarks and their functional significance in movement and stability of the upper limb.
