Midterm I: Lymph (Ben) Flashcards
What 3 main lymph vessels branch off of the thoracic and right lymphatic ducts near their junction with the angulus venosus?
Right and left…
- Jugular Trunks
- Subclavian Trunks
- Bronchomediastinal Trunks
What two main lymph vessels branch off the cisterna chyli inferiorly?
Lumbar Trunks
At what level is the cisterna chyli?
L1
To where does the upper lateral quadrant lymph of the breast drain?
What is the significance of this?
First to Sorgius Node, a “sentinal node” of the breast
Then to Axillary Nodes
- Palpating Sorgius node can be a good way to diagnose breast cancers.
Where exactly can Sorgius’ Node be found?
At the bottom of pec major around the 3rd digitation of serratus anterior
Most breast tumors are in what quadrant of the breast?
What percent?
95% are in the upper lateral quadrant
To where does lower lateral quadrant of the breast lymph drain?
Pectoral Nodes…
then to axillary nodes
What network of lymph vessels is found in the center of the breast?
Areolar Plexus
To where does medial quadrant breast lymph drain?
Both medial quadrants drain to…
Parasternal Nodes…
then to Supraclavicular Nodes
What parts of the body do the thoracic duct and right lymphatic duct drain?
Thoracic = Whole left side plus right leg and right lower abdomen
R Lymphatic Duct = Right side above lower abdomen
Describe the lymph drainage of the lung…
4 sets of nodes, plus where the 4th set drains to
- Intrapulmonary nodes, throughout lung, to…
- Bronchopulmonary nodes, in the hilum of each lung, to…
- Tracheobroncheal nodes, in angles btwn trachea + bronchi and btwn the 2 primary bronchi, to…
- Paratracheal nodes, along the length of the trachea, to…
… finally the Bronchomediastinal Trunk
Generally, what course does abdominal lymph take to get to the thoracic duct?
Nodes in the wall of or around abdominal organs drain to nodes which follow unpaired aorta branches.
(Celiac, Sup. Mes., Inf. Mes.)
Where does intraperitoneal organs’ lymph drain to generally?
Celiac Node –> Cisterna Chyli
Where do the inferior mesenteric nodes drain to?
Lumbar Trunk
Where does lymph from intraperitoneal organs draining to the superior mesenteric nodes then go to?
And retroperitoneal?
Intra: Sup Mes. nodes –> Celiac nodes –> C. Chyli
Retro: Sup. Mes nodes –> lumbar trunk
What are the 4 groups of nodes draining the stomach?
And their general locations.
- Left Gastric Nodes - around cardia + fundus
- Pancreatico-lienal Nodes - right side btwn stomach + spleen + running along pancreas
- Right Gastric Nodes - greater curvature
- Pyloric Nodes - around antrum + sphincter
Where do all the gastric nodes drain?
One set drains to two places.
Which set and to where?
All drain to cisterna chyli, but…
Left Gastric Nodes can also drain to vessels which travel through the esophageal hiatus to the posterior mediastinum and eventually to the left supraclavicular node of Virchow
What is the importance of the left supraclavicular node clinically?
And the name associated with it?
Swelling of …Virchow’s L. supraclavicular node…
can be indicative of stomach or medial left breast tumors.
