GIT HISTOLOGY-SMALL INTESTINE

1. Parietal cells of the stomach secrete HCl in response to gastrin.
2. G cells of the pyloric antrum and stomach release gastrin (also present in the duodenum & pancreas).
3. In the duodenum there are mucus-secreting glands of Brunner in the submucosa.
4. In the whole length of the small intestine the columnar epithelium dips down to form glands (crypts of Lieberkuhn) + thrown up to form villi.
5. At the bases of the crypts are granular Paneth cells - secrete lysozyme.
6. Scattered amongst crypt cells are endocrine cells (secrete secretin, somatostatin, CCK) + enterochromaffin (EC) cells (secrete histamine in response to gastrin stimulation).
