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
foregut and midgut

12

pelvic splanchnic nn

parasympathetic to GI tract from descending colon to proximal anal canal (hindgut)
preganglionic cell bodies S2-4
distribute through hypogastric plexus

13

sympathetics

T5-L2
utilize various prevertebral ganglia
postganglionic fibers distribute via aortic plexuses

14

greater splachnic n
