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