Flashcards in autonomics and lymph Deck (45):
1
celiac nodes
around celiac trunk
collect lymph from foregut
primary drainage is to intestinal lymph trunk
2
superior mesenteric nodes
around SMA
collect from midgut
primary drainage to celiac nodes
secondary drainage to intestinal trunk
3
inferior mesenteric nodes
around IMA
collect from hindgut
promary drainage to SM nodes
ssecondary to left lumbar trunk
4
intestinal lymph trunk
formed from efferent lymph channels of celiac nodes70% population drains to left lumbatr tunk
30% to cistern chyli
5
visceral nodes
celiac
SM nodes
IM nodes
intestinal lymph trunk
6
parietal nodes
common iliac
lumbar
7
common iliac nodes
collect from pelvis, perineum, LL
drain to lumbar nodes
8
lumbar nodes
lie along aorta (aortic) and IVC (caval)
collect from common iliac nodes, abdominal wall, kidney, ureter, suprarenal glands, some diaphragm, gonads, uterus, uterine tubes,
drain to right and left lumbar lymph trunks
9
lumbar trunks
left receives intestinal trunk and sometimes directly receives efferents from IM ndoes
left and right merge at LV2 to form thoracic duct
10
thoracic duct
forms anterior to LV2
enters thorax via aorta hiatus at TV12
11
vagus
enters through esophageal hiatus at TV10
