Document Summary
Describe the gross and microscopic anatomy of the stomach. Cardiac region- area from the cardiac orifice the top tube of stomach connecting to esophagus. Fundic region- dome the top of the stomach round part. Pyloric region- lower end divided into a funnel like atrium and a narrower pyloric canal. The pylorus connects the stomach into the duodenum the tube leading into the small intestine. Top layer of stomach tissue to bottom layer. Longitudinal muscle circular muscle oblique muscle gastric rugae. There are cardiac glands and pyloric glands in the same region and the rest of the stomach are called gastric glands. Remember the cardiac and pyloric glands secrete manly mucus while acid and enzyme and secretion occur predominately in the gastric glands. State the function of each type of epithelial cell in the gastric mucosa. Mucous cells- secret mucus in the cardiac and pyloric glands. Regenerative stem cells- divide rapidly and produce a continual supply of new cells.
