Q. No.Graves' disease is caused due to:
1. hyposecretion of thyroid gland
2. hypersecretion of thyroid gland
3. hyposecretion of adrenal gland
4. hypersecretion of adrenal gland
1. Insulin
2. Glucagon
3. Secretin
4. Gastrin
The posterior pituitary gland is not a 'true' endocrine gland because:
| 1. | it is provided with a duct |
| 2. | it only stores and releases hormones |
| 3. | it is under the regulation of hypothalamus |
| 4. | it secretes enzymes |
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. |

| 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. |
1. thyroxine and tri-iodothyronine
2. estrogen and progesterone
3. cortisol and cortisone
4. melatonin and serotonin
Which of the following pairs of hormones are not antagonistic (having opposite effects) to each other?

| (c) Relaxin | Inhibin |
| (d) Parathormone | Calcitonin |
| 1. | a | 2. | b |
| 3. | c | 4. | d |

3. Cholecystokinin and secretin
4. lnsulin and glucagon
1. Epinephrine
