Which of the following is NOT one of the four regions of the stomach?

The stomach is typically described using four main regions: the cardia at the junction with the esophagus, the fundus as the dome-shaped top, the body as the main central area, and the pylorus at the distal end leading to the duodenum. The antrum, while part of the pyloric region, is a subregion within that area (often called the pyloric antrum) and is not counted as one of the four primary regions. So, the statement that the antrum is not one of the four regions is correct. The antrum sits just before the pyloric canal and contains cells that help regulate digestion, such as gastrin-secreting G cells, which stimulate acid production downstream.
