Abdominal Organs & Abdominal Blood Vessels Flashcards
Name the arteries whose blood supplies define the foregut, midgut, and hindgut.
foregut (epigastric region): celiac trunk
midgut (umbilical region): superior mesenteric artery
hindgut (pubic region): inferior mesenteric artery
Name the alimentary organs that comprise the foregut.
esophagus, stomach, liver, duodenum 1, duodenum 2
Name the alimentary organs that comprise the midgut.
duodenum 3, duodenum 4, jejunum, ileum, cecum, ascending colon, transverse colon
Name the alimentary organs that comprise the hindgut.
descending colon, sigmoid colon
Name the “ligaments” found within the abdominal cavity.
greater omentum (gastrocolic ligament, gastrosplenic ligament, gastrophrenic ligament)
lesser omentum (hepatogastric ligament, hepatoduodenal ligament)
phrenicocolic ligament
mesenteries: transverse mesocolon, sigmoid mesocolon, mesoappendix, mesentery of the small bowel
What structures are associated with the gastrocolic ligament?
stretches between greater curvature of stomach and transverse colon
What structures are associated with the gastrosplenic ligament?
greater curvature of the stomach and hilum of the spleen
What structures are associated with the gastrophrenic ligament?
the portion of the greater omentum that extends from the greater curvature of the stomach to the inferior surface of the diaphragm
What structures are associated with the hepatogastric ligament?
connects lesser curvature of stomach with liver
What structures are associated with the hepatoduodenal ligament?
The hepatoduodenal ligament is the portion of the lesser omentum extending between the porta hepatis of the liver and the superior part of the duodenum
What structures are associated with the phrenicocolic ligament?
A fold of peritoneum, the phrenicocolic ligament is continued from the left colic flexure to the thoracic diaphragm opposite the tenth and eleventh ribs; it passes below and serves to support the spleen
What structures are associated with the transverse mesocolon?
connects transverse colon to posterior abdominal wall
What structures are associated with the sigmoid mesocolon?
The sigmoid mesocolon is the fold of peritoneum which retains the sigmoid colon in connection with the pelvic wall
What structures are associated with the mesoappendix?
The mesoappendix is the portion of the mesentery connecting the ileum to the appendix. It may extend to the tip of the appendix. It encloses the appendicular artery and vein, as well as lymphatic vessels, nerves, and often a lymph node
What structures are associated with the mesentery of the small bowel?
The mesentery is the double layer of peritoneum that suspends the jejunum and ileum from the posterior wall of the abdomen
What is the ligament of Treitz?
a suspensory muscle of the duodenum - serves to straighten out the duodenal-jejunal junction
Name the two spaces within the peritoneal cavity.
Greater peritoneal sac
Lesser peritoneal sac (“omental bursa”)
Name the 2 compartments of the greater peritoneal sac.
Supracolic compartment
Infracolic compartment
Name the 2 subdivisions of the lesser peritoneal sac.
Superior recess
Inferior recess
What is the “window” that connects the greater and lesser peritoneal sacs?
Omental foramen (of Winslow)
What are the 10 sets of vessels that arise from the abdominal aorta?
2-1-2-1-2 2-1-2-1 inferior phrenic arteries (2) celiac trunk (1) middle suprarenal arteries (2) superior mesenteric artery (1) renal arteries (2) gonadal arteries (2) inferior mesenteric artery (1) lumbar arteries (8) common iliac arteries (2) medial sacral artery (1)
What structures are associated with the phrenicoesophageal ligament?
esophagus & diaphragm
