Pyloric antrum
The pyloric antrum, or simply the antrum, is the 1-2 cm long proximal segment of the pyloric part of the stomach, beginning at the distal end of the body of the stomach and ending at the more distal of the two segments of the pyloric part, the pyloric canal.
The pyloric antrum is wider than the pyloric canal and contains the mucous-secreting pyloric glands that are unique to the antrum. These glands also contain enteroendocrine G cells which secrete gastrin. The antrum has few folds (rugae) which disappear when the stomach becomes distended.
