Dorsally, the first and the terminal interphalangeal articu- lations are opposite the most distal of the various creases overlying the joints. The most important muscular landmarks upon the front of the forearm are the brachio-raclialis, the flexor carpi radialis, and the pronator teres. The brachio- radialis is thrown into prominence by flexing the semi-prone forearm against resistance. At the junction of the proximal and middle thirds of the forearm the pronator teres passes beneath the brachio-radialis; between the two is the radial artery. The tendon of the flexor carpi radialis forms a prominent landmark descending along the middle of the volar aspect of the forearm towards the ridge of the multangular magus; the tendon of the palmaris longus, when present, is seen to its medial Please note that these images are extracted from
