Ulna and Radius

| View Cart ⇗ | Info

“The ulna, or elbow bone, is the larger of these two bones. It is joined to the humerus by a hinge joint at the elbow. It is on the same side as the little finger. The radius, queerly named because it is supposed to resemble one of the spokes of a wheel, is the long, slightly curved, outer bone fo the forearm. It is on the same side as the thumb. Its upper end is fastened both to the ulna and the humerus.” — Blaisedell, 1904
