Cat dissection. The cephalic vein (1) runs along the cranial surface of the antebrachium, flanked by lateral and medial branches of the superficial radial n. (2). After giving off an axillobrachial v. (3) that penetrates medially ventral to the deltoideus m., the cephalic v. (4) runs deep to the transected cleidobrachialis m. (asterisk) to join the external jugular v (5). (The cat lacks an omobrachial v. that, in the dog, runs on the surface of the brachiocephalicus m. to join the external jugular v.).
