Q

what is a peritoneal ligament

A
20
Q

what are the peritoneal ligaments of the liver

A

falciform ligament

continuous parts of lesser omentum

21
Q

what are the peritoneal ligaments of the stomach

A

continuous parts of greater omentum

22
Q

what are bare areas

why are they necessary

what dictates their location

A
23
Q

what are the peritoneal folds

A
24
Q

what are peritoneal fossa

A
25
Q

how is the peritoneal cavity divided

A

greater peritoneal sac - everything not in lesser sac

lesser peritoneal sac (omental bursa) - space behind lesser omentum, inbetween posterior stomach and anterior kidney

communicate via epiploic foramen

greater sac further divided into

supra colic infra colic - separated by mesentery of transverse colon, communicate through paracolic gutters

infra colic - separated into left and right by mesentery of small intestine

26
Q

describe the extent of the omental bursa

A

superior recess - limited by diaphragm and coronary ligament of liver

inferior recess - between greater omentum folds

27
Q

what is the function of the omental bursa

A

allows stomach to move freely on structures inferior and posterior to it

28
Q

where is the epiploic foramen

what are its borders

A

posterior to free edge of lesser omentum (where the hepatoduodenal ligament is)

anterior border - hepatoduodenal ligament

posterior - IVC (covered with peritoneum)

superior - liver

inferior - first part of duodenum

29
Q

what is the foregut, midgut, hindgut

A

all branches of abdominal aorta

foregut - coeliac axis

midgut - superior mesenteric

hindgut - inferior mesenteric

30
Q

what makes up the gastrointestinal tract

A

oesophagus, stomach, small intestine (duodenum, jejunum, ileum) and large intestine (cecum, appendix, ascending, transverse, descending, sigmoid, rectum, anal canal)

31
Q

what is the blood supply to the gastrointestinal tract

A

from abdominal aorta:

foregut - coeliac axis

midgut - superior mesenteric

hindgut - inferior mesenteric

32
Q

describe the blood supply coming from coeliac axis

A
33
Q

describe blood supply coming from superior mesenteric artery

A
34
Q

describe blood supply coming from inferior mesenteric artery

A
35
Q

describe venous drainage of GI tract

A
36

what are the constrictions of the oesophagus

A
37
Q

describe the muscle changes of the oesophagus

A
