Question

Brunner gland is characteristics feature of
A. Jejunum of small intestine
B. Ileum
C. Duodenum
D. Fundic region stomach

Answer 1

Hint: Brunner’s glands are submucosal glands. The function of this gland is to produce a mucous rich alkaline secretion. Food from the stomach enters into duodenum by a muscle called pyloric sphincter. The pyloric sphincter relaxes when the formation of chyme is completed and then chyme is squirted into duodenum.

Complete Answer:
- Brunner’s glands are found in the portion of duodenum which is above the sphincter of oddi. This gland produces a mucous rich alkaline solution. This gland protects the duodenum from acidic content of chyme.
- Brunner’ gland provides an alkaline condition for intestinal enzymes to be active. It lubricates the intestinal walls.
- Brunner’s glands empty into the intestinal glands. It exerts a physiologic anti acid function by coating the duodenal epithelium.
- These glands secrete pepsinogen and urogastrone which inhibit gastric acid secretion.
- Hyperplasia of brunner glands with a lesion greater than 1 centimetre was initially described as a brunner gland adenoma.
- Stomach has three regions- cardiac, fundus and pyloric. The fundus is the largest part of the stomach which has gastric glands.
- Brunner glands protect the intestinal walls from gastric juices.

So, the correct answer is C.

Note: Small intestine lies between stomach and large intestine. Small intestine is an organ where most of the end absorption of nutrients and minerals from food takes place. It is divided into three regions- duodenum, jejunum and ileum.
