Description
The lymph nodes of the back include the dorsal subtrapezoid, posterior scapular, and deep posterior scapular nodes. The subtrapezoid nodes drain lymph from the descending part of the trapezius, while the posterior scapular nodes drain the lower part of the trapezius and the rhomboid muscles. The deep posterior scapular nodes receive lymph from the supra- and infraspinatus muscles. The former two groups of nodes drain into the supraclavicular nodes, while the latter drain into the cervical subtrapezoid nodes. The deep muscles of the back drain into the intercostal and lumbar nodes.
