. Anatomy, descriptive and applied. Anatomy. THE RADIAL ARTERY 645 space between the metacarpal bones of the thumb and index finger, and finally passes forward, between the two heads of the First dorsal interosseous muscle, into the palm of the hand, where it crosses the metacarpal bones to the ulnar border of the hand, to form the deep palmar arch. At its termination it anastomoses with the profunda branch of the ulnar artery. The relations of this vessel may thus be conveniently divided into three parts—viz., in the forearm, at the back of the wrist, and in the hand. Relations.—In the forearm this vessel extends from opposite the neck of the radius to the fore part of the styloid process, being placed to the inner side of the shaft of the bone above and in front of it below. It is overlapped in the upper part of its course by the fleshy belly of the Brachioradialis muscle; throughout the rest of its course it is superficial, being covered by the integument, the superficial and deep fascije. In its course downward it lies upon the tendon of the Biceps, the Supinator [brevis], the Pronator teres, the radial origin of the Flexor subliniis digitorum, the Flexor longus polHcis, the Pronator quadratus, and the lower extremity of the radius. In the upper third of its course it lies between the Brachioradialis and the Pronator teres; in the lower two-thirds, between the tendons of the Brachioradialis and the Flexor carpi radialis. The radial nerve lies close to the outer side of the artery in the middle third of its course, and some filaments of the musculocutaneous nerve, after piercing the deep fascia, run along the lower part of the artery as it winds around the wrist. The vessel is accompanied by venae comites throughout its whole course. Plan of the Relations of the Radial Artery in the Forearm. In front. Skin, superficial and deep fasciae. Brachioradialis.
