    Incorrect

    • A 25 year old man presents to the emergency room with abdominal pain, vomiting and constipation. A CT scan is done which is suggestive of Meckel's diverticulum. Where does the blood supply of the Meckel's diverticulum originate?

      Your Answer: Gastroduodenal artery

      Correct Answer: Superior mesenteric artery

      Explanation:

      Meckel’s diverticulum has certain classic characteristics.1. It lies on the antimesenteric border of the middle-to-distal ileum2. It is approximately 2 feet proximal to the ileocaecal junction3. It appears as a blind-ended tubular outpouching of bowel4. It is about 2 inches long, 5. It occurs in about 2% of the population, 6. It may contain two types of ectopic tissue (gastric and pancreatic). 7. The diverticulum is supplied by the superior mesenteric artery.8. Proximal to the major duodenal papilla the duodenum is supplied by the gastroduodenal artery (branch of the coeliac trunk)9. Distal to the major duodenal papilla it is supplied by the inferior pancreaticoduodenal artery (branch of superior mesenteric artery).10. The arterial supply to the jejunoileum is from the superior mesenteric artery.

    Incorrect

    • The parasympathetic supply to the rectum is from which of the following:

      Your Answer: Sacral splanchnic nerves

      Correct Answer: Pelvic splanchnic nerves

      Explanation:

      Parasympathetic supply is from the pelvic splanchnic nerves (S2 – S4) and inferior hypogastric plexus.

    Correct

    • A patient is sent in by her GP with suspected ectopic pregnancy. Tubal ectopic pregnancies occur most commonly in which part of the uterine tube:

      Your Answer: Ampulla

      Explanation:

      Ectopic pregnancy most commonly occurs in the ampulla (70% of cases).

    Incorrect

    • Which of the following movements does the iliacus muscle produce?

      Your Answer: Extension of the trunk

      Correct Answer: Flexion of the thigh at the hip joint

      Explanation:

      The iliacus flexes the thigh at the hip joint when the trunk is stabilised. It flexes the trunk against gravity when the body is supine.

    Incorrect

    • A 68-year-old man with BPH presents to the emergency department in significant pain secondary to urinary retention. What is the location of the neuronal cell bodies that are responsible for urinary bladder discomfort sensation?

      Your Answer: Dorsal root ganglia of spinal cord levels L4 and L5

      Correct Answer: Dorsal root ganglia of spinal cord levels S2, S3 and S4

      Explanation:

      The activation of stretch receptors with visceral afferents relayed through the pelvic nerve plexus and into the pelvic splanchnic nerves causes bladder pain. The sensory fibres of spinal nerves S2 – S4 enter the dorsal root ganglia.

    Correct

    • The pelvic bone is formed by which of the following:

      Your Answer: Ilium, ischium and pubis

      Explanation:

      Each pelvic bone is formed by three elements: the ilium (superiorly), the pubis (anteroinferiorly) and the ischium (posteroinferiorly).

    Correct

    • Which of the following best describes the main sites of constriction of the ureters:

      Your Answer: At the ureteropelvic junction, at the pelvic brim and where the ureters enter the bladder

      Explanation:

      At three points along their course, the ureters are constricted denoting the most likely areas for renal calculi to lodge:the first point is at the ureteropelvic junction (where the renal pelvis becomes continuous with the ureter)the second point is where the ureter crosses the common iliac vessels at the pelvic brimthe third point is at the vesicoureteric junction (where the ureter enters the wall of the bladder)

    Correct

    • You are taking care of a 55-year-old male patient who is a weightlifter. He is suspected of having a direct inguinal hernia. Where would this hernia appear?

      Your Answer: Medial to the inferior epigastric artery

      Explanation:

      A direct inguinal hernia is a form of groin hernia that occurs when abdominal viscera protrude through a weakness in the posterior wall of the inguinal canal, notably through Hesselbach’s triangle, medial to the inferior epigastric veins.

    Incorrect

    • Which of the following describes the site of a Meckel's diverticulum:

      Your Answer: Second part of duodenum

      Correct Answer: Ileum

      Explanation:

      Meckel’s lies on the antimesenteric surface of the middle-to-distal ileum, approximately 2 feet proximal to the ileocaecal junction. It appears as a blind-ended tubular outpouching of bowel, about 2 inches long, occurring in about 2% of the population, and may contain two types of ectopic tissue (gastric and pancreatic). The rich blood supply to the diverticulum is provided by the superior mesenteric artery.Proximal to the major duodenal papilla the duodenum is supplied by the gastroduodenal artery (branch of the coeliac trunk) and distal to the major duodenal papilla it is supplied by the inferior pancreaticoduodenal artery (branch of superior mesenteric artery). The arterial supply to the jejunoileum is from the superior mesenteric artery.

    Incorrect

    • A tumour is discovered behind the pectinate line during an examination of a 72-year-old patient with rectal bleeding. Which of the following is the lymphatic drainage of the pectinate line?

      Your Answer: Deep inguinal nodes

      Correct Answer: Superficial inguinal nodes

      Explanation:

      The pectinate line is known as the watershed line because it divides the anal canal into two sections. Below the pectinate line, lymphatic drainage drains to the superficial inguinal lymph nodes.
