2. Both I and II are correct but II does not explain I
3. I is correct but II is incorrect
4. Both I and II are incorrect
Identify the correctly matched pair:
| Part of the pituitary | Hormone synthesized | |
| I: | Pars distalis | Gonodotropin releasing hormone |
| II: | Pars intermedia | Melanocyte stimulating hormone |
| III: | Pars nervosa | ADH and oxytocin |
| 1. | Only III | 2. | Only II |
| 3. | Only I and II | 4. | Only II and III |
| Assertion (A): | Oxytocin helps in parturition and causes milk ejection from the mammary glands. |
| Reason (R): | Oxytocin acts on the smooth muscles of our body and stimulates their contraction. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
| Assertion (A): | Apart from the organised endocrine glands, hormones are secreted by other parts of the human body as well. |
| Reason (R): | Hormone is any non-nutrient chemical which acts as intercellular messenger and is produced in trace amounts. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
| Assertion (A): | Vasopressin is also called as Anti Diuretic Hormone [ADH]. |
| Reason (R): | It is a vasoconstrictor. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
| Statement I: | Prolactin causes the milk ejection from the mammary glands. |
| Statement II: | Oxytocin regulates the formation of milk in the mammary glands. |
| Statement III: | FSH stimulates growth and development of ovarian follicles in females. |
| Statement IV: | MSH acts on melanocytes and regulates the secretion of melatonin. |

| I: | The adrenal cortical hormones are commonly called as corticoids. |
| II: | Cortisol is the main glucocorticoid and aldosterone the main mineralocorticoid in our body. |
| III: | Small amounts of androgenic steroids are also secreted by the adrenal cortex. |
