a. celiac artery the primative gut tube extends from the oropharyngeal membrane, cranially, to the cloacal membrane, caudally. It is divided into 3 main parts: foregut, midgut and hindgut. Each of these three segments is supplied by a single (unpaired) major arterial branch of the abdominal aorta. Most of the foregut is supplied by the celiac artery (trunk). thus, occlusion of this vessel will obstruct blood flow to the lower esophagus, stomach, liver, gallbladder, pancreas and proximal duodenum. Also, the celiac artery supplies the spleen, even though the spleen is not a derivative of the foregut. Most of the esophagus is located outside the abdomen and is supplied by local branches in the neck and thorax.

What blood vessel is most likely effected? a. celiac artery b. superior mesenteric artery c. inferior mesenteric artery d. portal vein e. umbilical vein
B. the superior mesenteric plexus is an autonomic netwreok around the badse of the superior mesenteric artery. Presynaptic sympathetic fibers synapse at this location, and post synaptic sympathetic fibers follow branches of this artery to distribute to the midgut organs, indlucing the ascending colon.

a 60 yo man is dx with a posterior abdominal wall tumor that is causing lesions in the superoir mesenteric plexus. Which of the following pathways is most likely affected? a. parasympathetic supply to the posterior aspect of the stomach b. sympathetic supply to the ascending colon c. lymph drainage from the liver d. venous drainage from the transverse colon e. visceral afferents from the proximal duodenum
E. the vagus nerve conveys parasymp. fibers to the gut tube and its derivatives as far distally as the left (splenic) flexure of the transverse colon. the second part of the duodenum is the only listed organ distal to the iatrogenic injury to the stomach but proximal to the left colic flexure. (parasymp loss)

a 78 yo man is brought to the ED by his wife. The man is doubled over with sudden onset of lower abdominal pain after eating dinner at an "all you can eat" buffet. The man's abdomen is distended, with vague lower left abdominal pain and he states that he cannot pass any gas. Bowel sounds are extensive in the upper abdomen, but are lacking in the left lower ab. The GI is asked to bring a sigmoidoscope. What condition does this patient have and how might a sigmoidoscope help? a. colitis; the sigmoidoscope will be able to visualize the lining of the rectum and colon and confirm the dx b. peptic ulcer; the sigmoidoscope will show a normal colon c. diverticulosis; the sigmoidoscope will be able to visualize the multiple diverticulua, thus confirming the dx d. meckel diverticulum; the sigmoidoscope will be able to visualize the typically 2 inch long diverticulum e. sigmoid volvulus; the sigmoidoscope may actually be used to help straighten the sigmoid colon if it has twisted on itself

Within the hepatoduodenal ligament, it parallels the bile duct and the portal vein. These 3 structures (portal triad) are enveloped within the free edge of the lesser omentum, specifically at its hepatoduodenal component.
during surgery to remove the gallbladder (cholecystectomy), a surgery resident damages the cystic artery before a clamp is properly placed. the attending physician applies pressure to the free edge of the hepatoduodenal ligament of the lesser omentum to control the bleeding until the damaged artery is clamped and ligated. Which of the following arteries was compressed by the attending? a. celiac b. splenic d. gastroduodenal d. common hepatic e. proper hepatic

d. esophageal vein
obstruction to portal blood flow through the liver would lead to dilation of which of the following structures? a. superior rectal artery b. common bile duct c. left colic a. d. esophageal vein e. main pancreatic duct f. inferior vena cava
b. enlargement of the GB is common complication of gallstone development. If the GB enlarges sufficiently and becomes inflamed then it can contact the inferior surface of the diaphragm, leading to right-sided shoulder/neck pain. The liver if inflamed would also produce right sided shoulder neck pain.
pathology within some abdominal organs can occasionally cause referred pain in the shoulder and neck regions, C3 to C5, because the diaphragm receives its motor and afferent innervation from this level as a result of its cranial embryonic development. Which one of the following abdominal organs causes unilateral shoulder/neck pain and which side of body is affected? a. liver; left side b. GB; right side c. pancreas; right side d. spleen; right side e. appendix; left side
A. the descengin colon is conrolled by the parasymp innervation from the pelvic splanchnic nerves. Control of peristalsis is principally a fn of the parasymp division of the autonomic nervous system
sympathectomy may occasionally relieve intractable pain of visceral origin, since visceral afferent pain fibers run along the symp pathways in the abdomen. The autonomic control of peristalsis in the descending colon should not be affected by bilateral lumbar sympathectomy for which one of the following reasons? a. the descending colon is controlled cheifly by parasymp innervation from the pelvic splanchnic nerves b. the descending colon receives its parasympathetic innervation from the vagus nerve c. the descending colon receives from L1, L2, and L3 only innervated the pelvic viscera via the hypogastric nerve only presynaptic sympathetic fibers have been severed
