Lymph Pathways Flashcards
Lateral aspect of the sole of the foot and the skin of the heel and lower calf
Popliteal- deep nodes
Skin of the posterior thigh
Directs to the front of the leg and drains into the superficial inguinal nodes
Skin over the lower abdomen ( below the navel- lumbar line)
Superficial inguinal nodes
Skin of the right arm
Drains into the axillary nodes
Skin of the left thumb
Cubital nodes, left venous angle where it empties into the left subclavian vein
If no swelling in thumb when thers edema in arm, bypasses axilla via radial pathway along cephalic vein to infra supra clavicular
Skin over the breast
Axillary nodes
Anterior intercostal spaces
Parasternal nodes to Thoracic duct
Medial portions of the mammary gland
The two medial quadrants drain into the retrosternal and parasternal nodes, thoracic duct
Skin of the posterior thorax
Drain lymph into the right and left axillary nodes
Posterior intercostal spaces
Drains lymph into the intercostal lymph nodes, which are located along the spinal column and usually empty into the thoracic duct
Skin of anterior thorax
Transport it via the infraclavicular lymph nodes to the venous angle or retrograde to the thoracic duct or cisterna chyli
Skin of the upper back above the spine of the scapular
Drain into the left and right axillary nodes
The lips
Submandibular lymph nodes , cervical lymph nodes, emptying in the venous angle
Skin of the right eyelid
Periauricular ( in front of ear at parotid)
Submandibular both are drawn into the deep cervial nodes
emptying from there into the venous angle.
The scalp
Through occipital lymph nodes along the nuchal line, to the superficial and deep cervical lymph nodes, emptying from there into the venous angle
The mesentery of the small intestine
intestinal trunk, to the cisterna chyli, joining into the thoracic duct
Urogenital organs
Iliac lymph nodes, into the right and left lumbar trunk to the cisterna chyli
The rectum
The lymphatic vessels of the upper half of the rectum ascends with the superior rectal blood vessels to reach the pararectal nodes and pass into the inferior mesenteric nodes. The lymphatic vessels of the lower half of the rectum up to the upper half of the anus travels via the middle rectal blood vessels to reach the internal iliac nodes. Others pierce the levator ani and accompany the internal pudendal and inferior rectal blood vessels to reach the internal iliac nodes. These nodes have efferents, which drain into the common iliac nodes and then the lateral aortic nodes. The lateral aortic nodes drain into lumbar nodes, which drain into the abdominal confluence of the lymphatic trunks or cisterna chyli. The cisterna chyli drains into the thoracic duct.
The lower concave surface of the liver
Drains to the nodes of the hepatic hilum
The testes
Iliac nodes , to lumbar trunks
Skin of external genitals
Superficial inguinal nodes to deep inguinal nodes
The heart
Via Bronchomediastinal trunk to left and right venous angle, to left and right lymphatic duct
Right lobes of the lung
Transported to right venous angle via the right bronchomediastinal trunk and the right lymphatic duct
Lower Left lobe of the lung
Follow left Bronchus via hilar nodes cross at the carina and join right Broncho mediastinal trunk to thoracic duct
The brain and spinal nerves
No lymph vessels in the brain or spinal cord so…
Cranial nerves lead the prelymph towards the ethmoid bone ( sieve like structure) 40-50% exits the skull with the olfactory nerve.
The rest is received by the nasopharyngeal area,and travels to the deep cervical nodes.
Sciatic pathway
Drains part of the back of the upper leg and empties into the iliac or the lumbar nodes of the abdomen, passing by the inguinal nodes. ( this is very important for patients with lymph stasis in the inguinal area.)
Paraspinal nodes…
Posterior intercostal pathways
Deep underneath the muscles
Capture any infected material near the pleural lining of the lung
Increase drainage from pleura( not when acute)
Upper portion of liver drains to…
Mediastinal nodes
Only thing in the diaphragm that doesnt drain into the abdominals
