Given below is an incomplete table on hormones, their source glands and one major effect of each human body. Identify the option representing correct grouping of hormone its gland and effect.

Gland	Secretion	Effect on body
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) - Ovary, (B) - Insulin, (C) Calcitonin
B
(A) - Placenta, (B) - Insulin, (C) - Vasoperssin
C
(A) - Ovary, (B) - Glucagon, (C) - Growth hormone
D
(A) - Placenta, (B) - Glucagon, (C) - Calcitonin

Answer

C. (A) - Ovary, (B) - Glucagon, (C) - Growth hormone
Explanation:
The correct option for the three blanks A, B, and C are ovary, glucagon and growth hormone respectively. Oestrogens are secreted by the Graafian follicle, which surrounds the mature ovum in the ovary. They stimulate the female reproductive tract to grow to full size and become functional. They also stimulate the differentiation of ova (oogenesis) in the ovary and stimulate the development of accessory sex characters such as enlargement of breasts, broadening of pelvis, growth of pubic and auxiliary hair, deposition of fat in the thigh; and onset of menstrual cycle. Glucagon is secreted by the alpha cells of the islets of Langerhans in response to a fall in the blood-glucose level. Somatotropic or growth hormone (STH or GH ) or somatotropin hormone is secreted by the anterior lobe of pituitary. Growth hormone stimulates growth and development of all tissues by accelerating protein-synthesis and celldivision and by retaining calcium in the body. Over secretion of growth hormone leads to gigantism.
