A
The splenic vein and pancreas are anterior to the superior mesenteric artery.
Just to the right of the sma the head of the pancreas wraps around the junction of the smv and splenic vein.

B. 2-3mm
C. 3-4mm
D. 4-5mm
B
5 to 7 mm thick in the antrum
The right adrenal gland is located posterior to which vessels?
A. Hepatic artery
B. Portal vein
C. Splenic artery
D. Inferior vena cava
D
At the level where the ivc enters the liver. The right adrenal gland is between the right lobe of the liver and the right crus of the diaphragm just above the upper pull of the right kidney.
The left adrenal gland lies just medial and anterior to the upper pole of the left kidney poster to the pancreas and splenic vessels and lateral to the cruise of the diaphragm.
Basing on the Couinaud classification of numbering of liver segments the following are true except:
A. Segment 1- Caudate lobe
B. Segment 3- left lateral superior segment
C. Segment 5- right anterior inferior segment
D. Segment 7- right posterior superior segment
B Segment 3- left lateral inferior segment
What do you call the smooth thickened muscular ridge that runs from the mouth of the SVC that fades inferiorly to the mouth of the IVC?
A. Crista terminalis
B. External sulcus terminalis
C. Interatrial septum
D. Fossa ovalis
A
What space or region is formed by a superficial layer of the deep cervical fascia that surrounds the muscles of mastication and the mandible extending from the angle of the mandible superiorly to the skull base?
A. Parotid space
B. Masticator space
C. Carotid space
D. Parapharyngeal space
B
The muscles of mastication involves the temporalis the medial and lateral pterygoid and the masseter.
In addition branches of the trigeminal nerve and the internal maxillary artery are located within this space
The normal ascending aorta arises in what position in relation to the main pulmonary artery
A. To the left of the main pulmonary artery
B. Posterior to the main pulmonary artery
C. Anterior and to the right of the main pulmonary artery
D. Posterior and to the right of the main pulmonary artery
D
Which cranial nerve runs parallel to the course of the posterior communicating artery?
A. Cranial nerve III
B. CN IV
C. CN V
D. CN VIII
A
The potential space between the visceral and parietal pleura normally contains a small amount of fluid. How much fluid is present within the pleural space?
Less than 5 ml
This fluid reduces the friction between the pleura
The trachea is approximately how many centimeters long in adults?
A. 10cm
B. 16cm
C. 20cm
D. 12 cm
D
About the length of a ruler*
What is the normal anatomic positioning of the heart called?
Situs solitus
What is the most dependent portion of the abdominal cavity in a supine patient?
Right hepatorenal fossa
By what month of age are the genu and splenium of the corpus callosum myelinated?
A. 3 months
B. 6 months
C. 9 months
D. 12 months
B
At 12-month-old the myelination is similar to an adult
The conventional diagnosis of ascites in radiographic imaging requires at least how much fluid to be present?
500 ml
In a newborn infant the transverse cardiac diameter may be up to how many percent of the transverse dimension of the chest measured between the inner rib margins?
60%
The cardio thoracic ratio decreases as the child grows older and should be less than 50% with the heart appearing similar to an adult by the second decade
