The pylorus is considered as having two parts, the pyloric antrum (opening to the body of the stomach) and the pyloric canal (opening to the duodenum). The pyloric canal ends as the pyloric orifice, which marks the junction between the stomach and the duodenum. The orifice is surrounded by a sphincter, a band of muscle, called the pyloric ...
Secretin is a hormone that regulates water homeostasis throughout the body and influences the environment of the duodenum by regulating secretions in the stomach, pancreas, and liver. It is a peptide hormone produced in the S cells of the duodenum, which are located in the intestinal glands . [ 5 ]
The pyloric gland is found in the pyloric region, the remaining 20 per cent of the stomach. The pyloric glands are mainly in the pyloric antrum. The pyloric gland secretes gastrin from its G cells. Pyloric glands are similar in structure to the oxyntic glands but have hardly any parietal cells.
The pylorus opens to the body of the stomach. The pylorus (from Greek 'gatekeeper') connects the stomach to the duodenum at the pyloric sphincter. The cardia is defined as the region following the "z-line" of the gastroesophageal junction, the point at which the epithelium changes from stratified squamous to columnar. Near the cardia is the ...
Antrum follicularum, the cavity in the epithelium that envelops the oocyte; Mastoid antrum, a cavity between the middle ear and temporal bone in the skull; Stomach antrum, either Pyloric antrum, the lower portion of the stomach. This is what is usually referred to as "antrum" in stomach-related topics [citation needed]
After removal of the distal portion (including the antrum and the pylorus) of the stomach, a clamp is fitted at right angles to the greater curvature. [9] The clamp is pushed far enough orally (towards the mouth) for the removal level to correspond in size to the duodenal lumen. [9]
The anterior gastric branches of anterior vagal trunk are branches of the anterior vagal trunk which supply the stomach. [1]One long branch of it runs from the lesser curvature or parallel to it in lesser omentum as far as the pyloric antrum to fan out into branches in a way like the digits of a crow's foot to supply the pyloric antrum and the anterior wall of pyloric canal.
A G cell or gastrin cell is a type of cell in the stomach and duodenum that secretes gastrin.It works in conjunction with gastric chief cells and parietal cells.G cells are found deep within the pyloric glands of the stomach antrum, and occasionally in the pancreas [1] and duodenum.
