Endocrine cells of the gastric oxyntic mucosa, and especially the enterochromaffin-like cells (ECL), are the progenitors of gastrin-promoted proliferative lesions whose tumorigenic potential largely depends on the background condition in which they arise.. Originating from the histamine-containing enterochromaffin-like (ECL) cells of the embryologic foregut, gastric carcinoid tumors represent

Gastrin itself is secreted by cells in the epithelium of the stomach, but travels to ECL cells via the blood. Gastric acid secretion is under nervous and hormonal control. Gastrin, the major circulating stimulus of acid secretion, probably does not stimulate the parietal cells directly but acts to mobilize histamine from the ECL cells in the oxyntic mucosa. Histamine stimulates the parietal cells to secrete HCl. No peptide product has been identified as yet in human ECL cells, although those of rodents are known to secrete histamine, which can be demonstrated using specific antibodies or antibodies against the enzyme histidine decarboxylase. Under the electron microscope, ECL cells are easily distinguishable from EC cells. Other articles where Enterochromaffin cell is discussed: human digestive system: Serotonin: …amino acid 5-hydroxytrytophan in the enterochromaffin cells (EC) and in other similar cells called enterochromaffin-like cells (ECL). These cells also secrete histamine and kinins, which likewise have important messenger functions in glandular secretions and on blood vessels.

Enteroendocrine cells are the hormone­ secreting cells present in the glands or mucosa of the gastrointestinal tract, particularly the stomach and intestine. The enteroendocrine cells present in gastric glands are G cells, EC cells, and ECL cells. FUNCTIONS OF GASTRIC GLANDS The function of the gastric gland is to secrete gastric juice. Start studying The stomach, acid secretion and ulcers.

Ecl cells secrete

The enterochromaffin-like (ECL) cells of the oxyntic mucosa (fundus) of the stomach produce, store and secrete histamine, chromogranin A-derived peptides such as pancreastatin, and an unanticipated but as yet unidentified peptide hormone. The cells are stimulated by gastrin and pituitary adenylate cyclase activating peptide and suppressed by somatostatin and galanin.

Enterochromaffin-like (ECL) cells Parietal cells [Choose ] secrete mucous Secrete H+ and CI- secrete gastrin secrete histamine and serotonin secrete pepsinogen [Choose Chief cells < Mucous neck cells [Choose) G cells [Choose] Prior to the recognition of the ECL cell as the pivotal regulator of gastric acid secretion, there was considerable confusion in regard to the mechanism by which the parietal cell was stimulated to secrete acid. The identification of the ECL cell and the recognition of its primary secretory product, histamine, dispelled the previous notion that 2020-06-09 · Definition. Goblet cells are a specialized type of epithelial cell that secrete mucins, which are significant components of mucus. They are most often found in the respiratory and gastrointestinal tracts, where they make up part of the surface epithelium. 類腸嗜鉻細胞( Enterochromaffin-like cells ),常簡稱ECL細胞( ECL cells )是一種胃黏膜上的神經分泌細胞,常分布於胃壁細胞附近。ECL細胞能分泌組織胺,輔助胃酸的分泌。這種細胞被認為屬於一種 腸道內分泌細胞 ( 英語 : enteroendocrine cells ) 。 參見 ECL cells are histamine‐containing endocrine/paracrine cells in the oxyntic mucosa of the stomach. They play a key role in the control of acid secretion because of their ability to secrete histamine, which stimulates adjacent acid‐producing cells (for reviews see Håkanson et al. 1994, 1998).

Answer: Enhances satiety, stimulates gallbladder contraction and pancreatic enzyme secretion, and inhibits gastric emptying and acid secretion. See Table 21.1 in the chapter. Enterochromaffin-like (ECL) cells produce histamine, which is important in the release of stomach acid. They are typically found in the base of the gastric glands. G-cells secrete the peptide hormone gastrin into the blood stream.

The histamine is released from the vesicles situated within the gastric mucosal cells. Histamine then stimulates the ECL cells to secrete hydrochloric acids.
