Bone Landmarks (Radius and Ulna)
ulna (elbow bone) is a long bone, prismatic in form, placed at the
medial side of the forearm, parallel with the radius.
Vinci, Arm Study, c. 1510
ulna articulates with:
humerus, at the elbow as a hinge joint.
radius, near the elbow as a pivot joint, this allows the radius
to cross over the ulna in pronation.
distal radius, where it fits into the ulna notch.
radius along its length via the interosseous membrane that forms
a syndesmoses joint.
