Abdomen Lymph/ANS Flashcards
Describe the superficial lymphatic drainage of the abdominal wall
above umbilicus to axillary
below umbilicus to superficial inguinal
What is the deep drainage of the abdominal wall
drain to external iliac, common iliac, and R/L lumbar nodes
How are preaortic nodes named
based on the vessel they are located by
What are intestinal and lumbar lymphatic trunks formed from
intestinal: preaortic nodes
lumbar: iliac, lateral aortic nodes, retroaortic
Where will both lumbar and intestinal lymphatic trunks drain
cisternae chyli
Where does the cisternae chyli drain
thoracic duct
What are the terminal nodes of the abdomen
celiac SMA IMA iliac Superficial inguinal lumbar
What will celiac nodes receive lymph from
foregut: gastric, hepatic, pancreosplenic
What will superior mesenteric nodes receive lymph from
midgut: mesenteric, iliocolic, right colic, and middle colic
What will inferior mesenteric nodes receive lymph from
left colic, sigmoid, and superior rectal nodes
Where will lymph from the testicles and ovaries drain
lumbar
para aortic/lateral aortic
Where will lymph from the scrotum and labia major drain
superficial inguinal
What will drain to the lumbar nodes
kidney
abdominal part of ureter
suprarenal
What is the function of sympathetics in the body wall
supply sweat glands of the skin and erector pilae for goosebumps
Where do organs of the abdomen receive postganglionic sympathetic axons from
pre-aortic ganglia
What types of fibers are seen in splanchnic nerves
preganglionic GVE
Where do preganglionic splanchnic nerves synapse
preaortic ganglia
What is the spinal cord level of greater splanchnic
T5-T9
What is the spinal cord level of lesser splanchnic
T10-T11
What is the spinal cord level of least splanchnic
T12
What is the spinal cord level of lumbar splanchnics
L1-L2
What spinal levels will supply the abdominal viscera
T5-L2, splanchnic nerves
What is the function of sympathetic innervation to abdominal viscera
shuts down GI tract during fight or flight
What is the pre-aortic plexus
network of nerves on top of the aorta
What does the greater splanchnic nerve supply
foregut; celiac ganglia/plexus
What does the lesser splanchnic nerve supply
mainly midgut; superior mesenteric ganglia
What does the least splanchnic nerve supply
mainly kidneys and upper ureter; aorticorenal ganglia
What do the lumbar splanchnic nerves supply
mainly hidgut; inferior mesenteric ganglia, renal, intermesenteric and hypogastric plexus
What nerves supply parasympathetic innervation to the gut
vagus: foregut and midgut
pelvic splanchnics: hindgut
Where do parasympathetics of the abdomen synapse
hypogastric plexus or organ
What spinal levels are seen in the pelvic splanchnic nerves
S2-S4
What type of axons are found in the ANS plexus
pre/post ganglionic
sympathetics and preganglion parasympathetics
What ganglia are included in the ANS plexus
sympathetic preaortic ganglia
