Match the following structure with their respective location in organs.
| Column I | Column II |
|---|---|
| (a) Crypts of lieberkuhn | (i) Pancreas |
| (b) Glisson’s Capsule | (ii) Duodenum |
| (c) Islets of Langerhans | (iii) Small intestine |
| (d) Brunner’s glands | (iv) Liver |
Select the correct option from the following
(a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)
(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
(a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)
Solution
The epithelia of the villi extend down into the lamina propria where they are responsible for the formation of crypts. Many of the important cells reside in the crypts. The liver capsule is composed of two adherent layers: a thick, fibrous inner layer called the Glisson capsule and an outer serous layer that is derived from the peritoneum.
Complete answer:
A) Crypt of Lieberkuhn are intestinal glands that are present in the mucosal epithelium of the intestine. Crypts are formed in between the villi and they are present at the base of villi.
B) Glisson’s capsule: These are the characteristic features of the liver. It is basically the layer of a connective tissue covering the liver. Hepatic arteries, portal vein and bile duct in the liver are also sheathed by the Glisson’s capsule.
C) Islets of Langerhans: Pancreas is the organ present in the abdominal cavity, behind the stomach. It is a part of both the digestive and endocrine system. The cells in the pancreas that have endocrine activity are called Islets of Langerhans. There are 4 different types of cells that constitute the islet of Langerhans (alpha, beta, gamma and delta cell).
D) Brunner’s gland: It is present in the submucosal part of the duodenum (part of the small intestine). These are multicellular cells. They secrete non-enzymatic substances which are alkaline in nature.
Therefore, the correct answer is option C.
Note: The wall of the alimentary canal is made up of four layers. The outermost layer is serosa followed by the muscularis layer, the submucosal layer and the innermost layer is the mucosal layer. The serosa is made up of thin epithelium tissue (mesothelium) and some connective tissue is also present.
