The axillary nodes are indicated by capital letters. The lateral nodes drain the upper limb. The subareolar plexus drains by collecting trunks into the axillary nodes. The pectoral nodes drain most of the breast. The apical nodes receive the lymph from the other axillary groups.Retropectoral (R) and transpectoral (T) routes are also shown.he subareolar plexus drains by collecting trunks into the axillary nodes. The pectoral nodes drain most of the breast. The apical nodes receive the lymph from the other axillary groups.
