A

the free border of the lesser omentum

23
Q

Which structures pass through the hepatoduodenal ligament?

A

portal triad: hepatic artery, portal vein and common bile duct

24
Q

What are the three types of umbilibal folds?

A
  • 1 median umbilical fold
  • 2 medial umbilical folds
  • 2 lateral umbilical folds
25
What is the median umbilical fold a remnant of?
the foetal urachus
26
What are the medial umbilical folds remnants of?
the umbilical arteries
27
What do the lateral umbilical folds overlie?
inferior epigastric arteries
28
How can the GI tract be divided?
into the foregut, midgut and hindgut
29
Where does the foregut run from?
the lower part of the oesophagus to the second part of the duodenum
30
What structures does the foregut contain?
liver, duodenum proximal to major papilla, spleen, gallbladder, pancreas, stomach
31
Where does the midgut run from?
from the second part of the duodenum to the distal third of the transverse colon
32
What structures does the midgut contain?
part of the pancreas, ileum, proximal 2/3 of transverse colon, duodenum distal to major papilla, hepatic flexure, caecum, jejenum, appendix, ascending colon
33
Where does the hindgut extend from?
the distal third of the transverse colon to the proximal part of the anus
34
What structures does the hindgut contain?
proximal part of anus, sigmoid colon, distal 1/3 of transverse colon, rectum, splenic flexure, descending colon
35
Blood supply to foregut:
coeliac trunk
36
Blood supply to midgut:
superior mesenteric artery
37
Blood supply to hindgut:
inferior mesenteric artery
38
Lymph drainage of each section of the gut corresponds to the names of arteries- what are the names of the nodes?
foregut- coeliac nodes midgut- superior mesenteric nodes hindgut- inferior mesenteric nodes
39
Where do the three main lymph nodes drain into?
intestinal lymph trunk
40
Where does the intestinal lymph trunk empty into?
the cysterna chyli (located at the end of the thoracic duct)
41
Where does the thoracic duct drain into the venous system?
junction between left subclavian vein and internal jugular vein
42
Autonomic innervation of the foregut:
preganglionic fibres originate at T5-T9; greater splanchnic nerve; coeliac ganglion
43
Autonomic innervation of the midgut:
preganglionic fibres originate at T10-T11; lesser splanchnic nerve; superior mesenteric ganglion
44
Autonomic innervation of the hindgut:
preganglionic fibres originate at T12-L1; lumbar splanchnic nerve; inferior mesenteric ganglion
45
Which nerve provides parasympathetic innervation of the gut?
vagus nerve
46
Which regional pains are associated with the structures of the gut?
foregut- epigastric region midgut- umbilical region hindgut- hypogastric region
47
What are the two plexuses of the enteric nervous system?
myenteric plexuses and submucosal plexuses
48
Where are the myenteric plexuses located?
Between the inner circular and outer longitudinal layers of the muscularis externa
49
What is the myenteric plexus responsible for?
gastrointestinal motility
50
What is the submucosal plexus responsible for?
senses environmental changes in the lumen and regulates GI blood flow and epithelial cell function
51
What is the role of the rugae in the stomach?
they expand to store food
52
What do the chies cells of the stomach do?
produce pepsinogen
53
Which branches of the coeliac trunk supply the stomach?
common hepatic artery, left gastric artery and the splenic artery
