| appendicular lymph nodes | Nodes along the appendicular vessels in the mesoappendix; they receive afferent vessels from the vermiform appendix and send efferent vessels to the ileocolic lymph nodes. Synonym: nodi lymphatici appendiculares. (05 Mar 2000) |
| axillary lymph nodes | Numerous nodes around the axillary veins which receive the lymphatic drainage from the upper limb, scapular region and pectoral region (including mammary gland); they drain into the subclavian trunk. Synonym: nodi lymphatici axillares, axillary glands. (05 Mar 2000) |
| bifurcation lymph nodes | Several large lymph nodes inferior to the tracheal bifurcation; they receive afferents from the bronchopulmonary nodes and the heart, and send efferents to the superior tracheobronchial and tracheal nodes. Synonym: nodi lymphatici tracheobronchiales inferiores, bifurcation lymph nodes, carinal lymph nodes. (05 Mar 2000) |
| brachial lymph nodes | Lymph nodes along the brachial vein that receive lymph drainage from most of the free superior limb and send efferent vessels to the central group of axillary lymph nodes. Synonym: nodi lymphatici brachiales, brachial lymph nodes. (05 Mar 2000) |
| bronchopulmonary lymph nodes | Lymph nodes in the hilum of the lung that receive lymph from the pulmonary node's, and drain to the tracheobronchial nodes. Synonym: glandulae bronchiales, bronchial glands, hilar lymph nodes, nodi lymphatici bronchopulmonales. (05 Mar 2000) |
