Here it is connected with the medial volar metacarpal artery, usually by two transverse branches, thus forming the deep volar or subcarpal arch (Arcus volaris profundus proximalis). One of these branches lies between the subcarpal check ligament and the suspensory ligament; the other (not always present) lies beneath the latter on the large meta- carpal bone. A small branch descends to the fetlock with the lateral volar nerve. Below the arch the artery pursues a flexuous course downward on the volar face of the large metacarpal bone alongside of the lateral small metacarpal and under cover of the suspensory ligament. At the distal third of the metacarpus it com- monly unites with the corresponding vessel of the other side to form a short trunk which passes backward through the angle of divergence of the branches of the sus- pensory ligament and joins the lateral digital or the common digital artery. This junction forms the distal volar arch (Arcus volaris distalis). 6. The medial volar metacarpal artery (A. metacarpea volaris medialis)^ is ^ Also termed the external metacarpal artery. 2 Also called the internal or small metacarpal artery. 42.
