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
Name a peptide hormone which acts mainly on hepatocytes, adipocytes and enhances cellular glucose uptake and utilisation:
| 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. |
Which one of the following hormones is not involved in sugar metabolism?
1. Cortisol
2. Aldosterone
3. Insulin
4. Glucagon
Which one of the following hormones though synthesised elsewhere, is stored and released by the master gland?
1. Melanocyte-stimulating hormone
2. Antidiuretic hormone
3. Luteinizing hormone
4. Prolactin
A chemical signal that has both endocrine and neural roles is:
2. calcitonin
3. epinephrine
4. cortisol
| 1. | Organs in the body like the gastrointestinal tract, heart, kidney and liver do not produce any hormones. |
| 2. | Non-nutrient chemicals produced by the body in trace amounts that act as intercellular messengers are known as hormones. |
| 3. | Releasing and inhibitory hormones are produced by the pituitary gland. |
| 4. | Adenohypophysis is under direct neural regulation of the hypothalamus. |
1. Low secretion of growth hormone
2. Cancer of the thyroid gland
3. Over secretion of pars distalis
4. Deficiency of iodine in diet
Select the answer which correctly matches the endocrine gland with the hormone it secretes and its function/deficiency symptom:
| Endocrine gland | Hormone | Function/deficiency symptom | |
| (A) | Posterior Pituitary | Growth Hormone (GH) | Oversecretion stimulates abnormal growth |
| (B) | Thyroid gland | Thyroxine | Lack of iodine in diet results in goitre |
| (C) | Corpus luteum | Testosterone | Stimulates spermatogenesis |
| (D) | Anterior pituitary | Oxytocin | Stimulates uterus contraction during childbirth |
1. (A)
2. (B)
3. (C)
4. (D)
