Anatomy and Physiology   The arterial pulse may be palpated in the extremities and the neck. With the knowledge of the contour of these vessels, the operator may easily identify the location of the artery. The anatomy of every site of insertion must be analyzed to determine the landmarks, the depth, the relationship to adjacent anatomical structures, and the size of the artery.     The radial artery is superficial in the thenar area of the wrist where the radial bone joins the metacarpal bones. There, the radial pulse is best felt slightly medial to the extensor tendons of the thumb. The radial artery is a preferred site of insertion.    The ulnar artery is opposite to the radial pulse in the volar aspect of the wrist at the joint of the ulnar bone to the metacarpal bones. The artery divides into 2 branches, both of which join a similar division of the radial artery to form a rich, collateral network known as the deep and superficial palma...
