Advanced Diaphragmatic Surface of the Spleen Quiz

Q1. Why is the diaphragmatic surface clinically relevant in fractures of the left ninth through eleventh ribs?

• The spleen lies within the pleural cavity
• The spleen lies immediately deep to these lower left ribs and diaphragm
• These ribs contain the splenic artery
• The spleen lies anterior to the sternum

Q2. Why can a surgical approach near the superior pole of the spleen risk entering the pleural cavity?

• The pleura passes through the splenic hilum
• The left pleural reflection descends near the diaphragm over the spleen
• The spleen is normally intrapleural
• The pleura is continuous with the splenic vein

Q3. How does the orientation of the diaphragmatic surface contribute to the spleen's oblique position?

• Its contour follows the diaphragm while the splenic long axis parallels the tenth rib
• It follows the inguinal ligament
• It is vertically suspended from the liver
• Its long axis parallels the linea alba

Q4. Why is the normal spleen often difficult to palpate?

• It is normally located in the pelvis
• It is enclosed within the kidney
• It lies behind the sacrum
• It lies high beneath the left costal margin and lower ribs

Q5. Which anatomical relationship explains synchronized splenic movement with respiration?

• Continuity of the spleen with the pleural cavity
• Attachment of the spleen to the trachea
• Fusion of the spleen to the vertebral column
• Direct apposition of the splenic surface to the diaphragm

Q6. Why should the diaphragm be inspected when managing penetrating trauma involving the diaphragmatic surface of the spleen?

• The spleen and thoracic cavity are separated by the diaphragm in this region
• The diaphragm contains the splenic artery
• The spleen lies entirely above the diaphragm
• The diaphragm forms the splenic hilum

Q7. Which relationship is most useful for distinguishing the diaphragmatic and visceral surfaces during gross examination?

• The diaphragmatic surface bears the renal impression
• The diaphragmatic surface is smooth and convex, whereas the visceral surface bears the hilum and impressions
• Both surfaces contain identical hilar structures
• The visceral surface is uniformly featureless

Q8. How does the costodiaphragmatic recess relate to the superior lateral spleen?

• It forms the gastrosplenic ligament
• It lies superior to the spleen across the diaphragm
• It lies within the splenic parenchyma
• It contains the splenic vein

Q9. Why is the diaphragmatic surface useful when interpreting splenic position on coronal imaging?

• Its convex contact with the left hemidiaphragm identifies the superolateral aspect
• Its relationship to the right kidney identifies the lateral surface
• Its continuation into the pancreatic duct defines the spleen
• Its contact with the urinary bladder identifies the superior pole

Q10. Which statement best integrates the anatomy of the diaphragmatic surface of the spleen?

• It is an uncovered retroperitoneal surface attached directly to the kidney
• It is a concave inferior surface lying in the pelvis
• It is the hilar surface containing the splenic vessels and pancreatic tail
• It is a smooth convex splenic surface with diaphragmatic, lower rib, pleural, pulmonary, and respiratory relationships
