Where is the celiac axis located anatomically?

  1. Beneath the diaphragm at approximately T8

  2. Beneath the diaphragm at approximately T10

  3. Beneath the diaphragm at approximately T12

  4. At the level of the umbilicus

The correct answer is: Beneath the diaphragm at approximately T12

The celiac axis is anatomically located at approximately the level of T12, just below the diaphragm. This artery originates from the abdominal aorta and supplies blood to several vital organs, including the stomach, liver, spleen, and parts of the pancreas and duodenum. The T12 vertebra serves as a key reference point for the celiac axis since it marks the transition from the thoracic to the abdominal cavity, where the diaphragm separates the thorax from the abdomen. This positioning is crucial for radiographic practices, as understanding the anatomy and location of significant vessels like the celiac axis is essential for proper imaging and interpretation in diagnostic radiography.
