Question 1

Which ligament divides the liver into right and left lobes on the anterior surface?

Accepted Answer

Falciform ligament

Answer

The falciform ligament is the peritoneal fold visible on the anterior liver surface that separates the anatomical right and left lobes.

Question 2

The adrenal glands are supplied primarily by branches of which vessels?

Accepted Answer

Inferior phrenic, aorta, and renal arteries

Answer

Each adrenal gland receives blood from three sources: the superior suprarenal (from inferior phrenic), middle suprarenal (from aorta), and inferior suprarenal (from renal artery).

Question 3

During fetal circulation, which structure allows oxygenated blood to bypass the pulmonary circulation by connecting the pulmonary artery to the aorta?

Accepted Answer

Ductus arteriosus

Answer

The ductus arteriosus connects the main pulmonary artery to the descending aorta, shunting blood away from the uninflated fetal lungs.

Question 4

Which muscle forms the floor of the posterior triangle of the neck and is an important landmark in neck sonography?

Accepted Answer

Omohyoid

Answer

The omohyoid muscle's inferior belly crosses the posterior triangle and serves as a key anatomical landmark separating neck compartments during ultrasound.

Question 5

The glomerular filtration rate (GFR) in a healthy adult is approximately:

Accepted Answer

125 mL/min

Answer

A normal GFR is approximately 125 mL/min (180 L/day), though most filtrate is reabsorbed with only about 1.5 L excreted as urine daily.
