The left subclavian trunk drains directly into the thoracic duct. The right subclavian trunk continues to form the right lymphatic duct and enters the right venous angle (junction of the internal jugular and subclavian veins) directly. The apical axillary nodes also receive lymph from those lymphatic vessels accompanying the cephalic vein.Įfferent vessels from the apical axillary nodes travel through the cervico-axillary canal, before converging to form the subclavian lymphatic trunk. They receive lymph from efferent vessels of the central axillary lymph nodes, therefore from all axillary lymph node groups. Apical – Located in the apex of the axilla, close to the axillary vein and 1st part of the axillary artery.They receive lymph via efferent vessels from the pectoral, subscapular and humeral axillary lymph node groups. Central – 3-4 large nodes, located near the base of the axilla (deep to pectoralis minor, close to the 2nd part of the axillary artery). They receive most of the lymph drained from the upper limb.
