Question: What type of cell is a stomach cell?

Disambiguated questions and answers:
context: Within the body and fundus of the stomach lie the "fundic glands". In general, these glands are lined by column-shaped cells that secrete a protective layer of mucous and bicarbonate. Additional cells present include parietal cells that secrete hydrochloric acid and intrinsic factor, chief cells that secrete pepsin, and neuroendocrine cells that secrete serotonin.

question: What is the type of cell in the stomach that protect the stomach from gastric acid?
short_answers: mucous cell

Long answers:
knowledge: content: Parietal cells (also known as oxyntic cells) are epithelial cells in the stomach that secrete hydrochloric acid (HCl) and intrinsic factor. These cells are located in the gastric glands found in the lining of the fundus and body regions of the stomach.

content: Gastric chief cells are generally located deep in the mucosal layer of the stomach lining, in the fundus and body of the stomach
wikipage: Gastric chief cell

content: A gastric chief cell (or peptic cell, or gastric zymogenic cell) is a type of gastric gland cell that releases pepsinogen and gastric lipase and is the cell responsible for secretion of chymosin in ruminants

content: Foveolar cells or surface mucous[a] cells are mucus-producing cells which cover the inside of the stomach, protecting it from the corrosive nature of gastric acid. These cells line the gastric mucosa (mucous neck cells are found in the necks of the gastric pits)

content: Enteroendocrine cells are located in the stomach, in the intestine and in the pancreas. 
wikipage: Enteroendocrine cell

content: Enteroendocrine cells are specialized cells of the gastrointestinal tract and pancreas with endocrine function.

long_answer: There are four types of stomach cells, parietal cells, gastric chief cells, mucous cells and enteroendocrine cells. Parietal cells which are also known as oxyntic cells are epithelial cells in the stomach that secrete hydrochloric acid and intrinsic factor. These cells are located in the gastric glands found in the lining of the fundus and body regions of the stomach. Another type of stomach cell, the gastric chief cell which is also known as a peptic cell or gastric zymogenic cell, is a type of gastric gland cell that releases pepsinogen and gastric lipase and is the cell responsible for secretion of chymosin in ruminants. Gastric chief cells are generally located deep in the mucosal layer of the stomach lining. Another type of stomach cell, foveolar cells or surface mucous cells are mucus-producing cells which cover the inside of the stomach, protecting it from the corrosive nature of gastric acid. These cells line the gastric mucosa. Another type of stomach cell, enteroendocrine cells are specialized cells of the gastrointestinal tract and pancreas with endocrine function. Enteroendocrine cells are located in the stomach, in the intestine and in the pancreas.
