"pylorus (antrum): the lower section of the stomach that facilitates emptying into the small intestine, located on the right of the midline at the level of L1."
"sympathetic innervation is from the T5 to T12 segments of the sympathetic chain via the greater and lesser splanchnic nerves which synapse in the coeliac plexus."
"mucosa: internal layer of epithelium, the lamina propria (loose connective tissue and gastric glandular tissue) and the muscularis mucosae"
"submucosa: a fibrous layer of connective tissue under the mucosa"
"muscularis externa: this is the muscular layer of the stomach wall and is comprised of three layers (inner oblique, middle circular and outer longitudinal) unlike other GI organs which only have two layers"
"serosa: the outermost layer of the stomach wall consisting of connective tissue which is continuous with the peritoneum"
"mucous cells: secrete a mucus gel layer and are found throughout the stomach"
"parietal (oxyntic) cells: secrete gastric acid and intrinsic factor throughout the stomach"
"chief (zymogenic) cells: secrete pepsinogen and rennin in the fundus and body 17"
"enteroendocrine (APUD cells): secrete a variety of products and are found throughout the stomach"
"gastrin: causes an increase in the secretion of hydrochloric acid (HCl), pepsinogen and intrinsic factor from parietal cells in the stomach; it also causes increased motility in the stomach; released by G-cells in the stomach to distension of the antrum, and digestive products; inhibited by a pH normally"
"cholecystokinin (CCK): greatest effect on the gallbladder, but it also decreases gastric emptying and increases release of pancreatic juice which is alkaline and neutralizes the chyme"
"secretin: has most effects on the pancreas, but will also diminish acid secretion in the stomach"
"gastric inhibitory peptide (GIP): decreases both gastric acid and motility"
"enteroglucagon: decreases both gastric acid and motility"
"glycogen: produced in the brain and stomach, affects the liver and level of glucose in the stomach"
"post-prandial patient"
"fundus: formed by the upper curvature; portion of stomach above GOJ level 17"
"enteroendocrine (APUD cells): secrete a variety of products and are found throughout the stomach"

"gastric inhibitory peptide (GIP): decreases both gastric acid and motility"
"may also appear round, with homogenous anechoic fluid filling the lumen"

"Sonographic localisation of the stomach is typically performed with epigastric transducer placement with the patient in a supine or right lateral decubitus position. The gastric antrum is commonly visualised just to the right of anatomic midline using the following sonographic landmarks; 11"
"There are two smooth muscle sphincters, oesophageal and pyloric, that dictate entry into and exit from the stomach. These are under the control of several mechanisms including stimulant (parasympathetic) and inhibitory (orthosympathetic) control from the anterior gastric, posterior, superior and inferior coeliac plexus and myenteric nerve plexuses."

"The stomach wall contains several different types of glandular tissue. The cardia, fundus and pylorus all have different types of glands and are composed of a variety of different cells:"
