Which of the following are not constituents within the root of the mesentery?
Superior mesenteric artery
Superior mesenteric vein
T11 SNS fibres
T12 SNS fibres
Of the mesenteric root
It divides the lateral colic gutters
It runs from the point delineating upper and lower GI bleeds clinically
It contains the inferior mesenteric vein
It contains T5 SNS afferents
The root of the mesentery runs inferolaterally to the
Jejunal peristalsis is partly regulated by
Autonomics of the coeliac plexus
Fibres running with the inferior mesenteric artery
PaNS T5 root value
The vagus nerve
A patient presents with fever, malaise and periumbilical pain localising to the right inguinal region. Which of the following is not an appropriate differential for the initial presentation?
Pancreatitis secondary to gallstones
Haemoperitoneum second to fallopian tubular ectopic rupture
Ileal diverticulum of Meckel
Question 5 Explanation:
The pattern of the pain is consistent with midgut involvement. The pancreas is the only organ that isn't a midgut structure and is therefore the right answer.
Which of the following is the appropriate surface anatomy of the initial bifurcation of the major arterial supply to the lower limb, abdominopelvis and perineum?
A patient has fallen off his horse and landed on his left side. Inspection reveals painful, tender and red ipsilateral flank signs with visible signs of hypovolaemic shock occurring on ED presentation by ambulance. The paramedic on scene ?fracture of L rib 10. Which organ should be first FAST-scanned (USS) to ascertain integrity?
An infection has tracked from the umbilicus through the patient's coronary ligament distally to the viscera of which it is associated. Which test would best indicate the true functionality of the now infected organ?
Oligoclonal band concentration
Question 8 Explanation:
The patient has hepatitis. Thus a true test of liver function, aka bilirubin, urea, PT time or albumin can be ascertained to check functionality decline - if any are present.
A patient begins iatrogenic exsanguination due to surgical complications in a liver lobar resection. What is the origin of the major supply of blood TOWARD the liver?
The superior mesenteric artery
T12, the coeliac trunk
Formed posterior to the neck of the pancreas
Question 9 Explanation:
The vast majority of blood travelling toward the liver is venous, not arterial, and thus is derived from the hepatic portal vein. There are a lot of anatomic varieties associated with this structure, but classically-speaking it is formed posterior to the pancreatic neck by the union of the splenic and superior mesenteric veins.
The following are not regions of localised dilatation and tortuosity at an anastomotic site in a patient with severe liver cirrhosis and secondary portal hypertension ...
Between the internal and external rectal venous plexuses
Between the left gastric and azygous venous branches
Between the coronary ligament venous branches and superficial epigastric veins
Between the inferior vena cava and hepatic vein
Question 10 Explanation:
Though note there is an oft-forgotten intrahepatic portocaval anastomosis where the ductus venous undergoes recanalisation to shunt into the IVC as in the foetus.
Name structures 6, 8, 9 respectively please ...
Common hepatic duct, hepatopancreatic ampulla and gallbladder
Common bile duct, hepatopancreatic ampulla and gallbladder
Pancreatic duct, hepatopancreatic ampulla and gallbladder
Common bile duct, major duodenal papilla and gallbladder
Which of the following is not a constituent of the lower urinary tract?
The external urethral sphincter
The renal pelvis
The urinary trigone
The cavernous urethra
Through which plane can a renal abscess spread bilaterally to include the other renal parenchyma and even vasculitis of the IVC and aorta?
Immediately superficial to pararenal fascia
Immediately superficial to prerenal fascia
Within the renal cortex
Only in pelvic kidney second to nephroptosis
A patient presents with haemoptysis, vomitus and severe pain score of 10/10 from the loin and migrating to the groin periodically. The patient is diagnosed, after imaging, with ureteric calculi. Which of the following sites is the least likely location of said stone?
The pelvicouterine junction
At the internal urethral sphincter
As the ureter cross the pelvic brim
As the ureter crosses the sacroiliac joint
