Question

Which of the following statements is not correct?

• A. Oxyntic cells are present in the mucosa of stomach and secrete HC1.
• B. Acini are present in the pancreas and secrete carboxypeptidase.
• C. Brunner's glands are present in the submucosa of stomach and secrete pepsinogen.
• D. Goblet cells are present in the mucosa of intestine and secrete mucus.

Answer 1

The Correct Option is C

To determine which of the provided statements is not correct, let's analyze each of them:

1. Statement 1: Oxyntic cells are present in the mucosa of the stomach and secrete HCl.
   This statement is correct. Oxyntic cells, also known as parietal cells, are located in the lining of the stomach and are responsible for secreting hydrochloric acid (HCl), which helps in digestion.
2. Statement 2: Acini are present in the pancreas and secrete carboxypeptidase.
   This statement is correct. Pancreatic acini are the exocrine cells of the pancreas that secrete digestive enzymes, including carboxypeptidase, into the small intestine.
3. Statement 3: Brunner's glands are present in the submucosa of the stomach and secrete pepsinogen.
   This statement is not correct. Brunner's glands are actually located in the submucosa of the duodenum, not the stomach, and they secrete an alkaline mucus to protect the duodenal lining and provide an optimal pH environment for enzyme activity.
4. Statement 4: Goblet cells are present in the mucosa of the intestine and secrete mucus.
   This statement is correct. Goblet cells are found in the lining of the intestine and are responsible for the secretion of mucus, which helps in the smooth passage of food through the digestive tract.

Based on the analysis above, the incorrect statement is: Brunner's glands are present in the submucosa of the stomach and secrete pepsinogen. This statement mislocates Brunner's glands and improperly describes their function.
