Diastole

Answer

Systole

Answer

Atrial contraction

Answer

Isovolumetric contraction

Question 6

Answer

15 mm

Answer

20 mm

Answer

50 mm

Question 7

Which of the following are recognized segments of the aorta?

Answer

Root

Answer

Ascending

Answer

Descending

Answer

Abdominal

Answer

Vena cava

Question 8

Which of the following is NOT a primary branch of the celiac trunk?

Accepted Answer

Superior mesenteric artery

Answer

Left gastric artery

Answer

Splenic artery

Answer

Common hepatic artery

Question 9

The right renal artery is typically shorter than the left renal artery because it passes anterior to the inferior vena cava.

Accepted Answer

False

Answer

True

Question 10

Which artery is considered the largest branch of the celiac trunk and is characterized by its tortuous path?

Accepted Answer

Splenic artery

Answer

Left gastric artery

Answer

Common hepatic artery

Answer

Gastroduodenal artery

Question 11

At approximately which vertebral level does the inferior mesenteric artery (IMA) typically arise from the abdominal aorta?

Accepted Answer

3rd or 4th lumbar vertebra

Question 12

Which of the following structures are supplied by the branches of the common hepatic artery?

Answer

Liver

Answer

Gallbladder

Answer

Stomach

Answer

Spleen

Question 13

In a sonographic transverse view, the superior mesenteric artery (SMA) is typically identified in what position relative to the abdominal aorta?

Accepted Answer

Answer

Posterior

Answer

Lateral

Answer

Medial

Question 14

Which anatomical feature distinguishes the Inferior Vena Cava (IVC) from the abdominal aorta during a sonographic examination?

Accepted Answer

The IVC is collapsible and lacks intrinsic pulsations.

Answer

The IVC is located to the left of the aorta.

Answer

The IVC has thicker, more echogenic walls than the aorta.

Answer

The IVC is formed by the union of the renal veins.

Question 15

At which vertebral level does the Inferior Vena Cava form through the union of the common iliac veins?

Accepted Answer

5th lumbar vertebra

Question 16

Why is the left renal vein anatomically longer than the right renal vein?

Accepted Answer

Because it must cross the midline between the abdominal aorta and the superior mesenteric artery to reach the IVC.

Answer

Because the left kidney is positioned significantly higher than the right kidney.

Answer

Because it receives drainage from the splenic vein before entering the IVC.

Answer

Because the left renal artery is shorter than the right renal artery.

Question 17

Which of the following vessels drain directly into the left renal vein?

Answer

Left suprarenal vein

Answer

Left gonadal vein

Answer

Right hepatic vein

Answer

Superior mesenteric vein

Question 18

The portal vein is formed by the junction of which two major veins?

Accepted Answer

Superior mesenteric vein and splenic vein

Answer

Inferior mesenteric vein and splenic vein

Answer

Superior mesenteric vein and hepatic vein

Answer

Left gastric vein and inferior mesenteric vein

Question 19

Sonographically, portal veins can be distinguished from hepatic veins by the presence of highly echogenic walls.

Accepted Answer

True

Answer

False

Question 20

Which veins drain the liver parenchyma directly into the Inferior Vena Cava?

Accepted Answer

Hepatic veins

Answer

Portal veins

Answer

Splenic veins

Answer

Renal veins
