Adenohypophysis Hypothalamus

Given ahead 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	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	Oversecretion leads to gigantism

Options:	A	B	C
1.	Placenta	Insulin	Vasopressin
2.	Ovary	Insulin	Calcium
3.	Placenta	Glucagon	Calcitonin
4.	Ovary	Glucagon	Growth hormone

GnRH, a hypothalamic hormone, needed in reproduction, acts on:

1.	Anterior pituitary gland and stimulates secretion of LH and FSH.
2.	Posterior pituitary gland and stimulates secretion of oxytocin and FSH.
3.	Posterior pituitary gland and stimulates secretion of LH and relaxin.
4.	Anterior pituitary gland and stimulates secretion of LH and oxytocin.

Hypersecretion of Growth Hormone in adults does not cause further increase in height, because?

1.	Epiphyseal plates close after adolescence.
2.	Bones lose their sensitivity to Growth Hormone in adults.
3.	Muscle fibres do not grow in size after birth.
4.	Growth Hormones become inactive in adults.

Which of the following hormones released from the pituitary is actually synthesized in the hypothalamus?

1.	Follicle-stimulating hormone (FSH)
2.	Adrenocorticotrophic hormone (ACTH)
3.	Luteinizing hormone (LH)
4.	Anti-diuretic hormone (ADH)
