    The interosseous membrane passes downwards and inwards (the opposite to the preceding) from the radius to the ulna ; it is attached to the interosseous ridge of each bone. Inferior Radio-idnar Articulation (lateral ginglymus). The anterior radio-ulnar ligament passes from the anterior edge of the radial sigmoid cavity to the anterior surface of the head of ulna. The posterior radio-ulnar ligament extends similarly upon the posterior surface. The triangular fihro-cartilage passes transversely beneath the lower end of the ulna, between the styloid process and the radius. Its apex is attached to the base of the styloid process, and the base to the edge of the radius between the sigmoid cavity and the lower end. The synovial membrane {memhrana sacci/ormis) is very loose, and lines the contiguous surfaces of the radius and ulna, together with the upper surface of the triangular cartilage ; sometimes communicates with the synovial sac of wrist-joint. YII.—THE WRIST-JOINT. The wrist-joint is a condyloid joint, formed by the lower end of the radius and the triangular fibro-cartilage above ; and by the scaphoid, semilunar and cuneiform bones below. It is united by the following ligaments :— The external lateral ligament passes from the tip of the styloid process of the radius to a depression on the outer surface of the scaphoid bone. The internal lateral ligament, a fibrous cord, passes from the end of the styloid process of the ulna, and dividing into two, one part is attached to the pisiform bone, and the other to the inner side of the cuneiform bone. The anterior ligament, broad and membranous, consists of three bundles of fibres, springing from the anterior edge of the lower end of radius, and the styloid process of the ulna ; below it is fixed into the anterior surfaces of the scaphoid, semilunar and cuneiform bones, some fibres being continued to the os magnum. The posterior ligament, weaker than the preceding, springs from the posterior margin of the lower end of the radius, and is attached to the dorsal surfaces of the scaphoid, semilunar, and cuneiform bones. A synovial membrane lines the joint. VIII.—ARTICULATIONS OF THE CARPUS. Articulations of the 1st Row of Carpal Bones, the pisiform excepted (arthrodial).
