Situated transversely behind the stomach; it produces and secretes insulin directly into the bloodstream
pancreas
28
Junction point between the stomach and the duodenum
pylorus
29
A ring of muscles that controls the passage of food from the stomach into the duodenum
pyloric sphincter
30

right colic vessels
31
The S-shaped end of the colon that leads into the rectum
sigmoid colon
32
Blood supply to and from the sigmoid colon; branch off of the inferior artery and vein
sigmoidal vessels
33
A coiled 20-foot-long tube that winds from the pyloric sphincter of the stomach to the beginning of the large intestine, filling much of the abdominal cavity, where the nutrients are removed from the bowel contents
small bowel
34
Located in the left upper quadrant; it breaks down the red blood cells and releases the hemoglobin
spleen
35
Lies between the esophagus and duodenum, stores food, located in the upper left quadrant
stomach
36
Blood supply to and from the right colon, liver, stomach, spleen and small bowel
superior mesenteric artery and vein
37
Extending from one side of the abdomen to the other
transverse colon
38
The navel or belly button
umbilicus
39
General term for contents of the abdomen
viscera
40
falciform ligament
a double-layered extension of parietal peritoneum that sweeps off the anterior abdominal wall to divide the liver into the asymmetric left and right lobes.
41
Where is the right colic flexure. Sometimes called hepatic flexure.
Fold between the ascending and transverse colon. Near the liver.
42
Where is the left colic flexure. Sometimes called splenic flexure
Fold between transverse colon and descending (left) colon. Near the spleen.
43
Name the four lobes of the liver.
left, right, caudate and quadrate
44
How many functionally independent segments of the liver, all receiving their own blood supply & lymph drainage?
8
45
Explain parietal vs visceral peritoneum
Your parietal peritoneum lines your abdominal and pelvic walls and your visceral peritoneum wraps around your organs. Your peritoneal cavity is the space in between.
46
What is the Greater Sac of the Peritoneum?
Distal to the Lesser Sac, the greater sac is the larger portion of the peritoneal cavity and comprises the majority of the peritoneal cavity. It is further divided into two compartments by the mesentery of the transverse colon (known as the transverse mesocolon): Supracolic compartment – lies above the transverse mesocolon and contains the stomach, liver and spleen. Infracolic compartment – lies below the transverse mesocolon and contains the small intestine, ascending and descending colon. The infracolic compartment is further divided into left and right infracolic spaces by the mesentery of the small intestine.
47
What is the Lesser Sac of the Peritoneum?
Lesser Sac (Omental Bursa) Proximal to the Greater Sac, the lesser sac lies posterior to the stomach and lesser omentum. It allows the stomach to move freely against the structures posterior and inferior to it. The omental bursa is connected with the greater sac through an opening in the omental bursa – the epiploic foramen (of Winslow). The epiploic foramen is situated posterior to the free edge of the lesser omentum (the hepatoduodenal ligament).
48
What is another name for Omental Bursa?
Lesser Sac (of the peritoneum)
49
The Greater Sac (of the Peritoneum) can be further divided into two compartments, name and describe what structures are housed in each compartment.
Supracolic compartment – lies above the transverse mesocolon and contains the stomach, liver and spleen. Infracolic compartment – lies below the transverse mesocolon and contains the small intestine, ascending and descending colon. The infracolic compartment is further divided into left and right infracolic spaces by the mesentery of the small intestine.
50
What is ascites?
While the peritoneal cavity is ordinarily filled with only a thin film of fluid, it is referred to as a potential space because excess fluid can accumulate in it, resulting in the clinical condition of ascites
51
What is another term for Cephalad? Hint: Used as an anatomical term when describing embryos. Hint: Cephalic
Cranial
52
What is the ligament of Treitz?
The ligament of Treitz is a thin band of tissue (peritoneum) that connects and supports the end of the duodenum and beginning of the jejunum in the small intestine
53
What is another term for the Biliopancreatic limb?
Duodenum
54
The Roux limb is also known as the...
Jejunum
55
What are the benefits of the Lembert suture technique?
Designed to encourage wound-edge inversion. Creates a natural crease. Used to recreate the alar creases and define the helical rim. Also useful when recreating the mental crease.
56
What is the Alar Crease? Not really related to any of the procedures you have covered...
Area of external skin where nostril meets cheek... alar = nostril
57
What is the helical rim? Not relevant to cases you will be covering
Curvature of the external ear
58
What is the mental crease? Not relevant to cases you will be covering
Also known as the chin crease, is the horizontal crease that forms between the lower lip and above your chin. This crease is formed by the chin's mentalis muscle and can be a single groove of varying depths, or in some people, may appear as multiple wrinkles or folds.
59
The surgical cutting open of the intestine.
Enterotomy
60
Surgical incision into the stomach.
Gastrotomy
61
The creation of an artificial external opening into the stomach for nutritional support or gastric decompression.
Gastrostomy
62
Endoscopy
Endo, a prefix from Greek ἔνδον endon meaning "within, inner, absorbing, or containing". An endoscope is a medical device with a light attached. It is used to look inside a body cavity or organ. The scope is inserted through a natural opening, such as the mouth during a bronchoscopy, or the rectum for a sigmoidoscopy. A medical procedure using any type of endoscope is called an endoscopy.
63
Name of dye agent used to visualise structures in surgery
Methylene Blue
64
What are cc a measure of?
Cubic centimeter = volume 1 cc = 1mL They are just different names for the same volume. One milliliter equals exactly one cubic centimeter.
65
What is the Petersen's defect?
Petersen's hernia is a type of internal hernia, in which part of the intestinal loop protrudes through a defect between small bowel limbs, transverse mesocolon, and retroperitoneum. It has been reported in individuals undergoing gastrojejunostomy (GJ), especially following bariatric surgeries
66
What is the main feature of a Jackson Pratt drain?
External bulb / balloon that allows patient to drain contents when full. Used in Laparoscopic Roux-en-Y Gastric Bypass sx. Drain is left in situ post sx until removed.
