Q

pancreas blood supply

Study These Flashcards
A

gets blood supply from both foregut and SMA

22
Q

midgut

Study These Flashcards
A

from major duodenal papilla to 2/3 distal transverse colon

23
Q

hindgut

Study These Flashcards
A

from 2/3 distal transverse colon to upper part/half way of anal canal

24
Q

oesophagus consrictions

Study These Flashcards
A

pharynx
arch of aorta
left main bronchus
diaphragm

25
oeso constriction: | 1. where Pharynx joins oesophagus
C6. 15 cm away from teeth
26
eoso constriction | 2. where arch of aorta crosses it.
T4. 22 cm away from teeth
27
oeso constriction | 3. where left main broncus crosses it.
T5. 27 cm away from teeth
28
oeso constriction | 4. at diagphragm oesophageal aperture.
T10.
29
oesophagus is behind?
trachea, aorta and left atrium of heart
30
where does venous blood of the lower 1/3 of the esophagus drain to?
– Left gastric vein | and then into Portal vein
31
– Functional sphincter
Lacks a localised thickening of muscle, so achieves contraction using external muscles around it the structures around it can compress
32
– Anatomical sphincter
Has a localised thickening of muscle
33
stomach muscle layers
innermost-oblique circular longitudinal
34
superior/first part of duodenum
"intraperitoneal" L1 COMMON SITE FOR DUODENAL ULCER attachment site for hepatodeuodenal ligament of lesser momentum
35
descending/2nd part of duodenum
L2 | where theres sphinctor of ODDi, MDP/ampulla of water
36
inferior/3rd part of duodenum
L3 | passes behind SMA
37
ascending/4th part of duodenum
L2 (curves upwards from L3 to L2) to join jejunum at DJ flexure
38
arterial supply of first part and to MDP of second part | of duodenum
superior pancreaticoduodenal
39
arterial supply of after MDP of second part, and third part and fourth part of duo
infeiror pancreaticoduodenal (from SMA)
40
jejunum where
left upper quadrant
41
ileum where
right lower quadrant
42
jejunum features
thicker heavier walls less mesenteric fat many place cirularis
43
ileum features
thinner lighter walls more mesenteric fat peyer's patches
44
jejunum vascularity
greater (fewer arcades longer vasa recta
45
ileum vascularity
poorer vascularity (more arcades shorter vasa recta
46
caecum -intraperitoneal or retro?
intraperitoneal
47
appendix-intraperitoneal or retro?
intraperitoneal
48
with mesentry
intraperitoneal | 'free'/mobile
49
without mesentry
retroperionteal | 'fixed'
50
poodle
SMV, IMV and splenic drain into portal vein
