Lecture 14 10/19/23 Flashcards
What are the three divisions of the peritoneum?
-parietal peritoneum
-visceral peritoneum
-connecting peritoneum (double layer)
Why does the tube that forms the intestines twist on itself?
to allow for the long tube of intestines to fit within a small space
Why is it important that the jejunum and ileum have longer connecting peritoneum?
allows for these sections to be moved more easily
What are the divisions of the stomach?
-cardia
-fundus
-body
-pylorus
What is the pyloric sphincter?
bulge of muscle separating the stomach from the intestines
What are the two curvatures of the stomach?
-lesser curvature
-greater curvature
What is the tissue that surrounds the stomach and covers the intestines?
greater omentum
What are the two parts of the omentum?
-superficial leaf
-deep leaf
What is the space between the two leaves of the greater omentum called?
omental bursa
Where does the greater omentum form, in relation to the stomach?
near the greater curvature
What is the function of the greater omentum?
to tack down on intestinal ruptures and seal them off (physiological band aid)
What portion of the duodenum comes right after the pyloric sphincter?
cranial duodenum
What is the curve of the duodenum between the cranial and descending duodena called?
cranial duodenal flexure
What is the curve of the duodenum between the descending and ascending duodena called?
caudal duodenal flexure
What are the sections of the small intestine?
-duodenum
-jejunum
-ileum
What does aborad mean?
away from the mouth
What does orad mean?
towards the mouth
What is the section between the duodenum and jejunum called?
duodenojejunal flexure
What is the name for the sphincter between the ileum and the colon?
ileocolic orifice
What is the name for the sphincter between the cecum and the colon?
cecocolic orifice
What is the first section of colon after the ileocolic orifice called?
ascending colon
What is the section of colon between the ascending and descending colon called?
transverse colon
Which section of colon is right before the pelvic cavity?
descending colon
What does the colon become once it crosses into the pelvic cavity?
rectum
What section is between the ascending and transverse colon?
right colic flexure
What section is between the transverse and descending colon?
left colic flexure
What is the role of the hepatic ducts?
to bring bile from the liver to the gall bladder
Where does the cystic duct become the bile duct?
after the last hepatic duct
Where are the major and minor duodenal papillae located?
descending duodenum
What structures open on the major duodenal papilla?
-bile duct
-pancreatic duct
What structures open on the minor duodenal papilla?
accessory pancreatic duct
How are the major and minor duodenal papillae oriented?
the major duodenal papilla is orad to the minor
