Question 1

Which structure of the biliary system is formed by the union of the common hepatic duct and the cystic duct?

Accepted Answer

Common bile duct

Answer

The common bile duct (CBD) is formed by the junction of the common hepatic duct and the cystic duct, and it drains bile into the duodenum.

Question 2

The rotator cuff is composed of four muscles. Which muscle is NOT part of the rotator cuff?

Accepted Answer

Teres major

Answer

The rotator cuff consists of the supraspinatus, infraspinatus, teres minor, and subscapularis; teres major is not a rotator cuff muscle and has a different innervation and function.

Question 3

On Doppler ultrasound, which waveform pattern is normally seen in the portal vein?

Accepted Answer

Monophasic continuous flow with mild respiratory variation

Answer

The normal portal vein shows continuous, predominantly hepatopetal (toward the liver) flow with gentle respiratory variation, distinct from the pulsatile arterial or triphasic hepatic vein patterns.

Question 4

The pyloric sphincter regulates the passage of chyme from the stomach into the:

Accepted Answer

Duodenum

Answer

The pyloric sphincter controls the rate of gastric emptying into the first part of the duodenum, allowing enzymatic digestion to keep pace with intestinal absorption.

Question 5

Which nerve is at risk of injury in the carpal tunnel and is assessed during median nerve ultrasound?

Accepted Answer

Median nerve

Answer

The median nerve travels through the carpal tunnel and is compressed in carpal tunnel syndrome; ultrasound can measure the nerve's cross-sectional area to support diagnosis.
