25
r. gastroduodenal -->
right side of the greater curvature of the stomach
26
superior pancreaticoduodenal a. --->
stomach, pancreas and the head of the duodenum
27
supraduodenal a. --->
superior duodenum, sometimes absent
28
r. gastric artery -->
right lesser curvature of the stomach
29
2 branches off of proper hepatic a.
1. right hepatic a. 2. left hepatic artery both to the liver
30
what does the cystic artery branch off of?
right hepatic a.
31
6! branches of the superior mesenteric a. in the midgut
1. inferior pancreaticoduodenal a. 2. intestinal branches 3. ileocolic a. 4. r. colic a. 5. middle colic a. 6. marginal a.
32
inferior pancreatico duodenal a. -->
head of pancreas and duodenum
33
intestinal branches -->
jejunum and ileum
34
ileocolic a. -->
distal ileum and cecum
35
r. colic a -->
ascending colon
36
middle colic a. -->
transverse colon
37
marginal a -->
ANASTOMOSING CIRCLE around the COLON
38
what gives rise to vasae rectae?
marginal a.
39
what connects the SMA and IMA? (besides aorta)
marginal a.
40
which branches of a. contribute to the marginal circle a.
ileocolic r. colic middle colic l. colic (**from IMA)
41
what are the three branches off of IMA?
1. l. colic 2. sigmoid a. 3. superior rectal a.
42
l. colic -->
descending colon
43
sigmoid a. -->
sigmoid colon
44
superior rectal aa -->
proximal rectum
45
anastomose between superior pancreaticoduodenal a. and inferior pancreaticoduodenal a. connect which two structures?
celiac trunk (sup) and superior mesenteric a. (inf)
46
what do the jejunal a. anastome with?
inferior pancreaticoduodenal a.
47
what does the anastomosis of superior rectal a., middle rectal a. and inferior rectal a. connect?
IMA (sup.), internal iliac (middle) and internal pudendal (inf)
48
blood from abdomen eventually returns to heart via IVC, but first it passes through
hepatic portal system
49
pathway of venous return to hepatic portal system
inferior messenteric vein --> splenic vein | superior mesenteric vein + splenic vein = hepatic portal v.
50
what is caput medusa? "snakes under skin"
non-functional umbilical veins fill with blood via umbilical anastomosis necessary due to liver enlargement
51
what do parasympathetics generally do in the abdomen
promote peristalsis and secretions
52
plexus of the foregut
celiac plexus T5-9
53
plexus of the midgut
superior messenteric plexus T10-12
54
plexus of hindgut
inferior messenteric plexus and hypogastric plexus (L1-2)(S2-4)
55
sympathetics of foregut
T5-9 pass through greater splachnic n. and synapse in celliac ganglia postsynaptics follow a. to target organ
56
parasympathetic of foregut
pass through vagus, celiac plexus, synapse in ganglia in the gut plexuses short post-synaptics
57
sympathetics of midgut
t10-12 pass through lesser t10-11 or least t12 sphlancnic nerve and synapse in superior mesenteric ganglion postsynaptics follow branches of SMA to organ
58
parasympathetics of midgut
pass through vagus nerve, superior messenteric plexus, follow branches of SMA to organ, synapse in gangli in gut plexuses shortpostynaptics
59
sympathetics of hindgut
arise from L1-2, pass through lumbar splanchnic nerves, synapse in inferior mesenteric gangliion postsynaptics follow branches of IMA to organ
60
parasympathetics of hindgut
arise from S234 pass through sacral spinal nerves, pelivc splanchnic nerves, branches to colon pass through hypogastric plexus and inferior mesenteric plexus, follow branches of IMA to target, synapse in gut plexuses short postsynaptics
