Question

At what spinal level are the following structures found

a) Celiac trunk
b) SMA exit
c) Transverse duodenum
d) IMA

Answer 1

Step-by-step explanation:

a) T12 vertebra

b) L1 vertebrae

c) L1-3

d) usually at L3.

Answer 2

The celiac trunk is found at the T12-L1 level, the superior mesenteric artery (SMA) exits at approximately L1, the transverse duodenum is located at the L1-L3 levels, and the inferior mesenteric artery (IMA) exits around the L3 level.

Step-by-step explanation:

The question pertains to the anatomical levels at which certain major arteries exit from the abdominal aorta and where the transverse duodenum is located relative to the spinal column. The abdominal aorta traverses down the abdomen, giving off several key arterial branches that supply blood to the abdominal organs.

• The celiac trunk is a major branch of the abdominal aorta that usually arises around the level of the T12 or L1 vertebra. It supplies blood to the liver, stomach, spleen, and the upper part of the duodenum.
• The superior mesenteric artery (SMA) exits the abdominal aorta at about the L1 level, shortly after the origin of the celiac trunk. It supplies blood to a large portion of the small intestine, the pancreas, and part of the large intestine.
• The transverse duodenum is located at the level of L1 to L3 vertebras.
• The inferior mesenteric artery (IMA) exits the abdominal aorta around the L3 vertebral level, supplying blood to the distal portion of the large intestine.
