Question

Structure preventing vertical descent of spleen

• A. Phrenocolic ligament
• B. Hepatogastric ligament
• C. Ligamentum teres
• D. Ligamentum flavum

Answer 1

The Correct Option is A

The spleen is an organ located in the upper left quadrant of the abdomen. It is held in place by various ligaments that stabilize its position. To understand which structure prevents the vertical descent of the spleen, let's consider the options:

• Phrenocolic ligament: This ligament extends from the left colic flexure to the diaphragm. It acts as a shelf, supporting the spleen, and prevents its downward movement due to gravity. By providing a lateral and slightly superior positioning, it prevents the spleen from descending vertically.
• Hepatogastric ligament: This is part of the lesser omentum, located between the liver and the stomach, and primarily stabilizes these organs.
• Ligamentum teres: This ligament is the remnant of the umbilical vein and is found in the liver, playing no direct role in supporting the spleen.
• Ligamentum flavum: These are ligaments found in the vertebral column, providing stability to the spine and not related to the spleen's position.

Based on this analysis, the phrenocolic ligament is the structure that prevents the vertical descent of the spleen by acting as a physical barrier or support under the organ.
