Hint: The gastric gland is the basic secretory unit of the stomach and contains a spread of component cells located in characteristic locations. The gland starts at the gastric pit, the opening to the lumen of the stomach.
Complete answer:
Gastric glands are branched tubular glands. These glands have a straight duct opening with branched clusters of secretory glands. They include the gastric glands of the stomach that produce acid, as well as the mucous secreting glands lining your esophagus, tongue, and duodenum of your small intestines. The gastric glands are situated in several areas of the stomach. The glands and gastric pits are located within the stomach lining. The glands themselves are within the lamina propria of the mucous membrane and that they open into the bottom of the gastric pits assembled through the epithelium. The varied cells of the glands release mucus, pepsinogen, HCl, intrinsic factor, gastrin, and bicarbonate.
Additional information: Gastric glands are present within the mucosa of the stomach. The following sorts of cells are present within the gastric gland. 1. Mucous neck cells – These cells secrete mucus, which is used to protect the mucosal epithelium from concentrated HCl. This concentrated HCl is released through the oxyntic cells. 2. Peptic (chief cells) – These cells release the proenzyme pepsinogen. Which is in an inactive form. This inactive proenzyme pepsinogen is activated by HCl and converted into the active kind of enzyme, which is named pepsin. Pepsin is employed to convert the proteins into proteases and peptones. 3. Parietal (oxyntic cells) – These cells release concentrated HCl and intrinsic factors. Intrinsic factors play an important role in the absorption of vitamin B12. HCL is used to activate the proenzyme pepsinogen.
So, the correct answer is '(c) Branched tubular'.
Note: The injury to oxyntic cells of gastric glands would end in pernicious anemia as oxyntic cells secrete intrinsic factors which are important for the absorption of vitamin B12. If any kind of damage happens to those cells than vitamin B12 won't be absorbed by the body, which can cause deficiency of B12 and can cause pernicious anemia.
