What area of the stomach is NOT associated with the presence of G cells?

The area of the stomach that is not associated with the presence of G cells is the antrum. G cells are specifically located in the gastric mucosa, primarily in two areas: the pylorus and the antrum of the stomach. They are responsible for secreting the hormone gastrin, which plays a key role in digestive processes by stimulating gastric acid secretion and promoting gastric motility.

While the pyloric region does contain G cells, the body and fundus of the stomach primarily contain other cell types, including parietal cells that secrete hydrochloric acid. The antrum is also known for its G cells, so this may create some confusion. However, it is the body and fundus where G cells are less concentrated, making it reasonable to assert that they are not primarily associated with the antrum in terms of their abundance.

In summary, the antrum does indeed contain G cells, confirming that a misunderstanding around this detail may have led to a misinterpretation of their distribution. The pylorus is recognized as a region rich in G cells, while the body and fundus, although they don’t contain them as prominently as the antrum and pylorus, still house these important hormone-secreting cells
