The stomach is the distal portion of which embryonic region?

The stomach is the distal portion of which embryonic region?

• A. Hindgut
• B. Foregut
• C. Midgut
• D. Neural tube

Answer: (B)

The stomach arises from the foregut portion of the primitive gut tube. The gut tube is organized into foregut, midgut, and hindgut regions, with the foregut giving rise to structures such as the esophagus, stomach, liver, pancreas, and the upper part of the duodenum. The stomach sits at the distal end of the foregut, between the esophagus and the duodenum. In contrast, the midgut forms much of the small intestine and part of the large intestine, and the hindgut forms the distal large intestine and beyond. The neural tube is unrelated to the gut derivatives. So the stomach is derived from the foregut.
