Description: (Location & Drainage)
The lateral group of superior diaphragmatic lymph vessels
receive lymph from the anterior superior surface of the diaphragm, as well as the inferior intercostal spaces, anterior upper surface of the liver, the superior part of the rectus abdominis muscle, and from the posteriorly located pericardium. The efferent vessels of this group send lymph to the parasternal lymph nodes via the prepericardiac lymph nodes or to the posterior group of diaphragmatic lymph nodes.
