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 |

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. |
