Question:
Islets of Langerhans are ________ .
Islets of Langerhans are ________ .
Show Hint
Pancreas = Dual gland
Islets $\rightarrow$ Hormones (endocrine)
Acini $\rightarrow$ Enzymes (exocrine)
Updated On: May 8, 2026
- groups of endocrine cells of pancreas
- group of cells in the stroma of thyroid gland
- star shaped glial cells of CNS
- grey masses within the white matter of nervous system
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept: The pancreas has both exocrine and endocrine components.
• Exocrine part: Acinar cells that secrete digestive enzymes.
• Endocrine part: Islets of Langerhans that secrete hormones.
Step 1: Understand Islets of Langerhans.
They are clusters of endocrine cells scattered throughout the pancreas.
Step 2: Identify their function.
• Alpha cells $\rightarrow$ Glucagon
• Beta cells $\rightarrow$ Insulin
• Delta cells $\rightarrow$ Somatostatin
Step 3: Analyze options.
• (A) Endocrine pancreas: Correct
• (B) Thyroid stroma: Incorrect
• (C) Glial cells: CNS support cells
• (D) Grey matter: Neural tissue
Step 4: Conclusion.
Thus, Islets of Langerhans are endocrine cell groups of pancreas. Final Answer: Option (A)
