Anatomical terminology

Thetracheobronchial lymph nodesarelymph nodesthat are located around the division oftracheaand mainbronchi.

Structure

These lymph nodes form four main groups includingparatracheal,tracheobronchial, bronchopulmonary and pulmonary nodes.

1. Paratracheal nodesare located on either side of the trachea.
2. Tracheobronchial nodescan be divided into three nodes including left and right superior tracheobronchial nodes, and the inferior trachiobronchial node. The two superior tracheobronchial nodes are located on either side of trachea just before its bifurcation. The inferior tracheobronchial node is located just below the bifurcation in the angle between the two bronchi.
3. Bronchopulmonary nodes(hilar nodes) situate in thehilumof each lung.
4. Pulmonary nodesare embedded thelungsubstance on the larger branches of the bronchi.

Theafferentsof the tracheobronchial glands drain the lungs and bronchi, the thoracic part of the trachea and theheart;some of the efferents of the posterior mediastinal glands also end in this group.

Theirefferentvessels ascend upon the trachea and unite with efferents of the internal mammary and anterior mediastinal glands to form the right and leftbronchomediastinal trunks.
