1

portal triad is within the

(proper hepatic artery, portal vein, common bile duct) hepatoduodenal ligament

2

gastrohepatic ligament is inside the

lesser omentum

3

falciform ligaments connects

liver to the anterior abd wall

4

gastrohepatic ligament connects

liver to lesser curvature of stomach; contains gastric arteries may be cut to access lower sac

5

gastrosplenic ligament

connects greater curvature to spleen; contains short gastrics and left gastroepiploics;

6

what separates greater and lesser sacs on the left?

gastrosplenic ligament

7

splenorenal ligament

connects spleen to posterior abd wall; contains splenic vessels

8

to control bleeding in portal triad, you can compress the..

hepatoduodenal ligament (pringle maneuver)

9

layers of gut wall from inside to outside

MSMS mucosa (epithelium, lamina propria, muscularis mucosa) submucosa (includes submucosal plexus = meissners) muscularis externa (includes myenteric plexus = auerbachs plexus) serosa (when intraperitoneal)/adventitia (when retro)

10

muscularis externa has two layers -->

inner circular layer outer longitudinal layer

11

plicae circularis are where?

jejenum and proximal ileum

12

peyers patches are where?

ileum

13

largest number of goblet cells in small intestine?

ileum

14

colon has _____ but no ____

crypts of lieberkuhn; villi

15

SMA syndrome

transverse (3rd) part of duodenum gets trapped between SMA and aorta --> causes intestinal obstruction

16

top to bottom middle three: celiac trunk (t12), SMA (L1), IMA (L3)

right : right renal a, right gonadal a

left: left inferior phrenic a, left middle suprarenal a, left gonadal a, left common iliac --> int and ext iliac a

bottom: mediac sacral a

bifurcation at L4

17

foregut artery and parasympathetic innervation

celiac 

vagus

18

midgut artery and innervation

SMA and vagus

19

hindgut artery and innervation

IMA and pelvic nerve

20

branches of celiac trunk

common hepatic, splenic and left gastric

21

signs of portal HTN

varices of gut, butt, caput (esophagus, umbilicus, and rectum)

 

left gastric --> esophageal

paraumbilical --> epigastric veins of anterior abd wall (caput medusae)

superior rectal --> middle and inferior rectal (anorectal varices - NOT internal hemorrhoids)

22

hiatal hernia

stomach herniates up through esophageal hiatus in diaphragm

23

indirect inguinal hernia

through internal inguinal ring

24

direct inguinal hernia

through inguinal triangle

25

where are the stem cells of GI tract?

stomach vs intestines?

intestinal crypts

higher in the stomach vs in the pit of the gland of intestines

26

secretory cell that is secreting hormones to influence GI function

enteroendocrine cell

27

enteroendocrine cells are sensitive to? secrete out which side?

sensitive to luminal contents

secrete out basal side

28

secretory cell involved in host defense?

paneth cell

29

paneth cell

secretory cell involved in host defense located close to the lumen where pathogens are located

30

intrinsic innervation of the GI tract?

enteric nervous system
