Question 1

Which cell type in the pancreas produces glucagon?

Accepted Answer

Alpha cells

Answer

Alpha cells in the islets of Langerhans secrete glucagon, which raises blood glucose by stimulating hepatic glycogenolysis and gluconeogenesis.

Question 2

On ultrasound, the normal pancreatic duct diameter should not exceed:

Accepted Answer

3 mm

Answer

The main pancreatic duct (duct of Wirsung) normally measures ≤3 mm in adults; dilation beyond this raises concern for obstruction or chronic pancreatitis.

Question 3

Which hormone, secreted by the posterior pituitary, regulates water reabsorption in the kidney collecting ducts?

Accepted Answer

Antidiuretic hormone (ADH)

Answer

ADH (vasopressin) acts on aquaporin channels in the collecting duct to increase water reabsorption and concentrate urine.

Question 4

The right ovarian vein drains directly into the:

Accepted Answer

Inferior vena cava

Answer

Unlike the left ovarian vein (which drains into the left renal vein), the right ovarian vein drains directly into the inferior vena cava, mirroring gonadal vein asymmetry seen in males.

Question 5

Which tendon is evaluated at the posterior ankle and is the largest tendon in the body?

Accepted Answer

Achilles tendon

Answer

The Achilles (calcaneal) tendon is the thickest and strongest tendon in the body, connecting the gastrocnemius and soleus muscles to the calcaneus.
