Object nameWrist, Mounted wet bone and tissue
DescriptionThe left wrist-joint of a duck-billed platypus.
The scaphoid and lunar are fused to form a single bone articulating with the radius and to a slight extent with the ulna. Two large lateral prominences on its proximal surface engage with corresponding depressions upon the radius and ulna, while the groove between them is occupied by a process of the radius. This interlocking between the proximal row of carpals and the bones of the fore-arm restricts the movements of the wrist to simple flexion and extension
