Trace the entire vascular network of the arm and hand - in three dimensions. Superior in every way to two-dimensional charts or diagrams, this full-scale plastic rendering of the left arm and hand includes, in addition to the skeletal components, the brachial, radial, and ulnar arteries and their tributaries, plus all the accompanying veins. In addition to accurately reproducing their comparative diameters, blood vessels have been color-coded - arteries red, veins blue - and tagged for identification in the accompanying key. Supported on a stand in the semi-flexed position, the arm lifts off for unobstructed observation from all aspects.
