Description
The deep vessels of the forearm are named according to the artery that they accompany; radial, ulnar, and posterior and anterior interossei lymph vessels.
The deep radial lymph vessels collect lymph from the deep lymphatic palmar arch of the hand, whilst the deep ulnar lymph vessels collect lymph from the superficial palmar arch. The interosseous lymph vessels accompany both the anterior and posterior interosseous arteries.
During their course, the deep forearm lymphatic vessels will divide into two or three branches, which unite proximally as they ascend into the arm. The deep vessels drain lymph into the cubital lymph nodes, and then proximally into the brachial lymph vessels.
