Q

COMPONENTS OF EMBRYONIC FOREGUT

Including and up to:

A 
Stomach
Duodenum (first bend of small intestine)
Liver
Gall bladder
Pancreas
50
Q

Pancreas originally two separate lobes explain

A

(ventral part of hepatic diverticulum, dorsal independent.

51
Q

Rotation brings ______ tail and ventral components of ______ together.

A

dorsal pancreas

52
Q

Hepatic Diverticulum

A

know anatomy- listen to the lecture
The hepatic diverticulum (or liver bud) is a primordial cellular extension of the embryonic foregut endoderm that gives rise to the parenchyma of the liver.

53
Q

As elongate midgut exits, it rotates ___ degrees counterclockwise about the ________ _________ _______

A

90, superior mesenteric artery

54
Q

As elongate midgut re-enters, it rotates 180 degrees

A

counterclockwise about the Superior Mesenteric Artery.

55
Q

COMPONENTS OF EMBRYONIC MIDGUT

Including and up to:

A

Jejunum and Ileum of small intestine
Appendix
Ascending Colon
Transverse Colon (up to LEFT COLIC FLEXURE)

56
Q

Hepatic Portal Vein and Its

Tributaries

A

inf mesenstic, sup mesenteric, splenic vein

57
Q

Most of the internal organs are surrounded by visceral peritioneum what condition?

A

the INTRAPERITONEAL condition.

58
Q

Some organs (e.g. kidneys) are between peritoneum on one surface, and the body wall on the other what condition?

A

the RETROPERITONEAL condition

59
Q

STRUCTURES WITHIN THE PELVIS

name

A

End of digestive system
Female reproductive organs
Bladder
Ducts to, and exiting from, bladder

60
Q

pyloric sphincter

A

The pyloric sphincter is a thin, circular band of visceral muscle surrounding the pyloric opening at the inferior end of the stomach. It is found at the border of the stomach’s final segment, the pylorus, and the small intestine’s first segment, the duodenum..

61
Q

The greater omentum

A

is a large apron-like fold of visceral peritoneum that hangs down from the stomach. It extends from the greater curvature of the stomach, passing in front of the small intestines and reflects on itself to ascend to the transverse colon before reaching to the posterior abdominal wall. The greater omentum is larger than the lesser omentum which hangs down from the liver to the lesser curvature.

62
Q

heaptic portal vein

A

is the system of veins comprising the hepatic portal vein and its tributaries. It is also called the portal venous system, although it is not the only example of a portal venous system, and splanchnic veins, which is not synonymous with hepatic portal system and is imprecise

63
Q

bile duct

A

the duct that conveys bile from the liver and the gallbladder to the duodenum.

64
Q

left colic flexture

A

The splenic (or left colic) flexure is a sharp bend between the transverse and the descending colon in the left upper quadrant of humans. The left colic flexure is near the spleen, and hence called the splenic flexure. There are two colic flexures in the transverse colon — the other being the hepatic flexure, as it is next to the liver, in the right upper quadrant.

65
Q

more info about stuff

A

The ventral mesentery forms the lesser omentum, and is attached to the developing liver. In the adult, these connective structures of omentum and mesentery form the peritoneum, and act as an insulating and protective layer while also supplying organs with blood and lymph vessels as well as nerves.

66
Q

liver

A

develops in ventral mesentary,filter all of the blood you absorb goes to liver first, endodermal cells will make the liver growing of liver splits mesentary

67
Q

faliciform ligament

A

part of ventral mesentary, above liver, attached to body wall, still attaches to part of old ventral margin of liver and body wall has been streatched to right

68
Q

less omentun

A

part of gut and liver called lesser omentum

69
Q

mesentarys never

A

deaatch from their original connections

70
Q

lesser omentrum

A

runs between liver and gut tube, never change attachments ever ever changes from vertical to horizontal never deattaches

71
Q

greater omentum

A

overgrows, no longer suspends guts The greater omentum (also the great omentum, omentum majus, gastrocolic omentum, epiploon, or, especially in animals, caul) is a large apron-like fold of visceral peritoneum that hangs down from the stomach. overstretches into a big floppy bag- primary reason: attached to guts/stomach mostly, put lots of bad stuff full of immune system components lots of lymphatic tissue

72
Q

epiolic foramen

A

The epiploic foramen (also called the foramen of Winslow) is a passage between the greater (general peritoneal space) and lesser sac (omental bursa) allowing communication between these two spaces.

73
Q

stomach between liver

A

lesser omen

74
Q

midgut

A

in the region of the midgut because of the umbelical hernia the ventral mesentary is lost

75
Q

Retroperitoneal
components of
abdominal cavity

A

Retroperitoneal
components of
abdominal cavity
digestive
esophagus (thoracic part, part inside abdominal cavity is intraperitoneal)
rectum (part, lower third is extraperitoneal)
