Explanation: Neuronal control is done by secretion of acetylcholine by the cholinergic neuron. Hormonal control of gastric acid is done by gastrin. Paracrine control of gastric acid is done by histamine secreted by enterochromaffin-like cells.

Explanation: H. pylori primarily colonize in the antrum of the stomach it resides mainly within the gastric mucus. H. pylori have a high activity of the enzyme urease which enables it to colonize in the stomach. Infection can spread through fecal route. Infection thought to occur between parents and young children.

Explanation: The majority of cases of peptic ulcer disease are related to H. pylori. The diagnosis of H. pylori infection must be confirmed prior to initiation of therapy. The methods can be histology and culture, antibody test, urease CLO test. H. pylori have a high activity of the enzyme urease which enables it to colonize in the stomach. Infection can spread through fecal route. Infection thought to occur between parents and young children.

Explanation: Peptic cells in the stomach lining is also known as a chief cell. The stomach lining has parietal cells that secrete acid, Goblet cells, mucous neck cells, superficial epithelial cells. All these cells can be found in the body and fundus of the stomach.

Explanation: Neuronal control is done by secretion of acetylcholine by the cholinergic neuron. Hormonal control of gastric acid is done by gastrin. Paracrine control of gastric acid is done by histamine secreted by enterochromaffin-like cells.

Explanation: Cholinergic neuron secretes acetylcholine that through circulation goes and bind to the muscarinic receptor in the parietal cell secrete acid into the gastric lumen. Enterochromaffin-like cells secrete histamine which again goes and binds to the H2 receptor and through the cAMP pathway helps the parietal cell to secrete acid. Gastrin secreted by Antral G cell is the hormonal control of acid secretion by the parietal cell. Gastrin, Histamine, and acetylcholine switch on the proton pump thus pumping H+ ions to produce acid in the gastric lumen.

Explanation: Cholinergic neuron secretes acetylcholine that through circulation goes and bind to the muscarinic receptor in the parietal cell secrete acid into the gastric lumen. Enterochromaffine like cells secrete histamine which again go and bind to the H2 receptor and through the cAMP pathway helps the parietal cell to secrete acid.

Explanation: Enterochromaffine like cells secrete histamine which again go and bind to the H2 receptor and through the cAMP pathway helps the parietal cell to secrete acid. Gastrin secreted by Antral G cell is the hormonal control of acid secretion by parietal cell. Acid in our stomach is secreted by the parietal cells. Mucous is secreted by the goblet cells.

Explanation: Gastrin secreted by Antral G cell is the hormonal control of acid secretion by parietal cell. Gastrin, Histamine and acetylcholine switch on the proton pump thus pumping H+ ions to produce acid in the gastric lumen. Acid in our stomach is secreted by the parietal cells. Mucous is secreted by the goblet cells.

Gastrin secreted by Antral G cell is the hormonal control of acid secretion by parietal cell. Gastrin, Histamine and acetylcholine switch on the proton pump thus pumping H+ ions to produce acid in the gastric lumen.

Explanation: H+, K+-ATPase is located in the apical membrane of the oxyntic cell along the secretory canaliculi. The pump requires large amounts of energy that is supplied by intracellular ATP that is why inhibition of H+, K+-ATPase blocks both basal and stimulated acid secretion.

Explanation: Cimetidine is an H2 receptor antagonist thus used in the treatment of peptic ulcer. It inhibits basal acid secretion of the stomach including nocturnal secretion. It is readily absorbed after oral administration and has a brief duration of action from 4-8 hr.
