There are fourteen in number, three for each [[finger]], and two for the [[thumb]]. Each consists of a body and two extremities. * The ''body'' tapers from above downward, is convex posteriorly, concave in front from above downward, flat from side to side; its sides are marked by rough areas which give attachment to the fibrous sheaths of the flexor tendons. * The ''proximal extremities'' of the bones of the first row present oval, concave articular surfaces, broader from side to side than from front to back. The [[proximal]] extremity of each of the bones of the second and third rows presents a double concavity separated by a median ridge. * The ''[[distal]] extremities'' are smaller than the proximal, and each ends in two [[condyles]] separated by a shallow groove; the articular surface extends farther on the [[volar]] than on the [[dorsal]] surface, a condition best marked in the bones of the first row. The ungual phalanges, those most distal, are convex on their dorsal and flat on their volar surfaces; they are recognized by their small size, and by a roughened, elevated surface of a horseshoe form on the volar surface of the distal extremity of each which serves to support the sensitive pulp of the finger. ==See also== * [[Interphalangeal articulations of hand]] * [[Phalanx bones]] ==Additional images== <gallery> Image:Gray337.png|Metacarpophalangeal articulation and articulations of digit.
