Q. Given below is an incomplete table about certain hormones, their source glands and one major effect of each on the body in humans. Identify the correct option for the three blanks A, B and C. Gland A – Oestrogen – Maintenance of secondary sexual characters Alpha cells of Islets of Langerhans – B – Raises blood sugar level Anterior pituitary – C – Over secretion leads to gigantism
A) A: Placenta, B: Glucagon, C: Calcitonin
B) A: Ovary, B: Glucagon, C: Growth hormone
C) A: Placenta, B: Insulin, C: Vasopressin
D) A: Ovary, B: Insulin, C: Calcitonin
Explanation
[Solution from source] Oestrogen that maintains female secondary sexual characters comes from the ovary, the α-cells of the islets of Langerhans secrete glucagon which raises blood sugar, and over-secretion of growth hormone from the anterior pituitary causes gigantism. Insulin lowers blood sugar, and calcitonin is from the thyroid. Answer (2).
