The celiac trunk and superior mesenteric artery are anatomically distinct
Anatomical and radiological studies confirm that the celiac trunk and the superior mesenteric artery are distinct major ventral branches of the abdominal aorta, though rare variants like a celiacomesenteric trunk can occasionally occur.
The claim states that the celiac trunk and superior mesenteric artery are anatomically distinct. The retrieved anatomical and radiological studies consistently treat them as separate vessels arising independently from the aorta (while noting occasional rare variations like a common trunk), thus supporting the claim of distinct anatomical structures.
