The hormones secreted by Islets of Langerhans are?

Correct option is B

Sol. The Islets of Langerhans in the pancreas secrete Insulin (β-cells), Glucagon (α-cells), and Somatostatin (δ-cells). These hormones regulate blood glucose and digestive enzymes. Somatostatin controls both insulin and glucagon release. ACTH is secreted by the anterior pituitary and plays no role in pancreatic function.
Explanation of each option:
· (a) Insulin, Glucagon – Partially correct, but misses Somatostatin, which is essential for hormonal regulation.
· (b) Insulin, Glucagon, Somatostatin – Correct. These are the three key hormones from the islet cells of the pancreas.
· (c) ACTH – Adrenocorticotropic hormone is produced by the pituitary gland and stimulates the adrenal cortex.
· (d) ACTH, Somatostatin – Incorrect, as glucagon is essential and ACTH doesn’t originate in the pancreas.
