105. Celiac trunk. Superior and inferior mesenteric arteries
Walks through the abdominal aorta from its start at the aortic hiatus to its bifurcation at the fourth lumbar vertebra, then sets out its visceral and parietal branches. The visceral branches are listed as single and paired groups, with the celiac trunk, superior and inferior mesenteric arteries and their branches to the stomach, liver, spleen and pancreas, alongside the adrenal, renal and gonadal arteries. Two pictures accompany the outline.
