Q. No.A hormonal disorder that develops when pituitary gland produces too much growth hormone during adulthood is known as:
1. cretinism
2. gigantism
3. Conn’s syndrome
4. acromegaly
All the following regarding parathyroid glands are true except:
| 1. | They usually include four small glands. |
| 2. | They are embedded in the posterior surfaces of the lateral lobes of the thyroid gland. |
| 3. | They secrete parathyroid hormone and calcitonin. |
| 4. | They play a critical role in calcium homeostasis. |
The peptide thyroid hormone that lowers calcium and phosphate ion concentration in the blood is:
| 1. thyroxine | 2. triiodothyronine |
| 3. calcitonin | 4. thyroid-stimulating hormone |
Hormones are chemical messengers of all classes except:
| 1. | peptide | 2. | steroid |
| 3. | aminated | 4. | carbohydrate |
Which one of the following pairs correctly matches a hormone with a disease resulting from its deficiency?
| 1. Relaxin-Gigantism | 2. Prolactin-Cretinism |
| 3. Parathyroid hormone-Tetany | 4. Insulin-Diabetes insipidus |
Identify the incorrectly matched pair:
|
1. |
Hyposecretion of growth hormone in childhood |
Dwarfism |
|
2. |
Hyposecretion of growth hormone in adulthood |
Cretinism |
|
3. |
Hypersecretion of growth hormone in childhood |
Gigantism |
|
4. |
Hypersecretion of growth hormone in adulthood |
Acromegaly |
The only hormone secreted by pars intermedia of hypophysis is:
| 1. MSH | 2. GnRH |
| 3. Vasopressin | 4. Prolactin |
The definition of hormone describes them as having all the following features except:
1. non-nutrient chemicals
2. intra-cellular messengers
3. produced in trace amounts
4. act on distant target organ
ADH and oxytocin are synthesized by:
| 1. Anterior pituitary | 2. Hypothalamus |
| 3. Pars intermedia | 4. Pars nervosa |
Which of the following endocrine glands is under direct neural regulation of hypothalamus?
| 1. Pineal | 2. Adrenal medulla |
| 3. Posterior pituitary | 4. Anterior pituitary |
