head; towards its anterior and convex surface is a remark-
able eminence, termed the styloid process of the radius.

Cavity. The glenoid cavity at its inferior extremity : it is
divided into two by a slight transverse rising. On the anterior
and external surface of the lower extremity, are several
grooves, in which the tendons of some of the muscles of the
fore-arm pass. A fossa, on the opposite side to the styloid
process, which receives the rounded surface of the ulna j a fo-
ramen, about three or four inches from its upper end, for the
passage of the medullary vessels.

Joints. The elbow-joint is constituted by three bones; the
inferior extremity of the humerus, and the superior extremi-
ties of the radius and niia, which are inclosed in a ligamen-
tous bag, called the capsular ligament, besides which there is
a coronary ligament peculiar to the head of the radius, and
the joint is strengthened by the two lateral ligaments, a quan-
tity of cellular substance, muscles, and tendons.

Its motions are like unto an hinge, the radius and ulna bend-
ing backwards and forwards upon the humerus. The radius
has another motion, viz. that of rotation, which it performs
upon the ulna.

The joint is supplied with synovia.

Use. To assist in forming the fore-arm, and to serve for
flexion, supination, and pronation.

Connexion. The radius is connected to the humerus by
ginglymus, to the cubit by an interosseous ligament and tro-
choides, and to the carpus by arthrodia.

Both extremities of this bone are epiphyses at birth.

THE HAND.

The b^nes of the hand consist of those of the carpus, meta-
carpus, and fi ngers.
