Thorax Lymphatic Drainage Flashcards
What are the 5 lymph nodes of the breast?
- parasternal
- inguinal
- infraclavicular
- axillary
- apical axillary
What are the 4 thoracic, parietal lymph nodes?
- parasternal
- intercostal
- diaphragmatic
- posterior mediastinal
What are the 4 thoracic, visceral lymph nodes?
- pulmonary
- bronchopulmonary
- tracheobronchial (inferior and superior)
- paratracheal
Function of the parasternal lymph nodes (breast):
drain medial breast bilaterally
Function of the inguinal lymph nodes:
may * drain inferior breast
located in LE
Function of the infraclavicular lymph nodes:
may drain superior breast
Function of the axillary lymph nodes:
(pectoral, humeral, subscapular, central)
PREDOMINANT drainage of the breast
Function of the apical axillary lymph nodes
Drain superior breast and other axillary nodes
Function of the parasternal (thoracic, parietal lymph nodes)
drains medial breast (bilaterally) , upper abdominal wall, anterior pleura and part of liver
Function of intercostal lymph nodes (thoracic, parietal lymph nodes)
drain lateral and posterior thoracic wall
Function of posterior mediastinal lymph nodes (thoracic, parietal lymph nodes)
drain pleura and esophagus
Function of diaphragmatic lymph nodes (thoracic, parietal lymph nodes)
drain liver, pleura, and diaphragm
Function of pulmonary lymph nodes (thoracic, visceral lymph nodes):
drains the lung
Function of the bronchopulmonary lymph nodes (thoracic, visceral lymph nodes)
drain pulmonary nodes and bronchi
Function of the tracheobronchial lymph nodes (inferior and superior) (thoracic, visceral lymph nodes)
drain bronchopulmonary & posterior mediastinal nodes, trachea, & heart
Function of the paratracheal lymph nodes (thoracic, visceral nodes):
drain tracheobronchial nodes
Function of the cisternal chyli:
receives lymph from preaortic and retroaortic lymph nodes (details in Clinical Anatomy II) and lower extremities (via left and right lumbar trunks) and **provides origin to thoracic duct
What are the two main lymphatic ducts of the thorax region?
thoracic duct
right lymphatic duct
Function of the thoracic duct:
** IMPORTANT:
drains nodes of the right and left lower extremities, pelvis, abdomen, left thorax, left upper extremity, and left head and neck (via cisterna chyli, left jugular, left subclavian, and left bronchomediastinal trunks)
Function of the right lymphatic duct:
drains nodes of the right thorax, right upper extremity, and right head and neck.
Forms at union of right jugular, right subclavian, and right bronchomediastinal trunks
What is the primary lymphatic trunk in the thoracic region?
The bronchomediastinal (right and left) trunk
Function of the bronchomediastinal trunk:
drains parasternal, diaphragmatic, and thoracic visceral nodes
