capitate bone

These movements take place through a transverse axis passing through the capitate bone.

The capitate bone is the largest of the carpal bones in the human hand, and occupies the center of the wrist.

Malformation of the wrist bones (fusion of the hamate and capitate bones).

Both radial abduction and ulnar adduction occurs around a dorsopalmar axis running through the head of the capitate bone.

The hand is said to be in straight position when the third finger runs over the capitate bone and is in a straight line with the forearm.

The oblique head (Latin: adductor obliquus pollicis) arises by several slips from the capitate bone, the bases of the second and third metacarpals, the intercarpal ligaments, and the sheath of the tendon of the flexor carpi radialis.

The medial surface presents two articular facets; of these, the superior or smaller is flattened, of semilunar form, and articulates with the lunate bone; the inferior or larger is concave, forming with the lunate a concavity for the head of the capitate bone.

Features not present in the hands of extant or fossil apes include hand length, relative thumb length, a deep and large insertion for the flexor pollicis longus, and the shape of the carpometacarpal joint between the metacarpal bone of the index finger and the capitate bone.
