Definition for Celiac artery
From Biology Forums Dictionary
The celiac (or coeliac) artery, also known as the celiac trunk, or truncus coeliacus, is the first major branch of the abdominal aorta. It is 1.25 cm in length, in a horizontal direction. Branching from the aorta anterior to the upper border of L1 vertebra (almost immediately after entering the abdominal cavity through the diaphragm at T12) in humans, it is one of three anterior/ midline branches of the abdominal aorta (the others are the superior and inferior mesenteric arteries).
