. Anatomy, descriptive and applied. Anatomy. For 4th metacarpal Palmar surface Fig. 159.—The left os magnum. A, outer side seen from below; B, internal posterior surface. internal surface articulates with the unciform by a smooth, concave, oblong facet which occupies its posterior and superior parts, and is rough in front, for the attachment of an interosseous ligament. To ascertain to which hand this bone belongs, the rounded head should be held upward, and the broad dorsal surface forward; the internal concave articular surface will point to the side to which the bone belongs.

To ascertain to which hand this bone belongs, the rounded head should be held upward, and the broad dorsal surface forward; the internal concave articular surface will point to the side to which the bone belongs. Articulations.—With seven bones—the scaphoid and semilunar above; the second, third, and fourth metacarpal below; the trapezoid on the radial side; and the unciform on the ulnar side. Attachment of Muscles.—Part of the Adductor obliquus pollicis. The unciform {os hamahim) (Fig. 160) may be readily distinguished by its wedge-shaped form and the hook-like process that projects from its palmar surface. It is situated at the inner and lower angle of the carpus, with its base downward, resting on the two inner metacarpal bones, and its apex directed upward and outward. For semilunar. For cuneifor? For OS magnum—.
