ACTH controls the secretion of ........................
| 1. Cortisol | 2. Aldosterone |
| 3. Epinephrine | 4. Testosterone |
Which of the following is not a feature characteristic of the anterior pituitary?
| 1. | It synthesizes and releases tropic hormones. |
| 2. | It is controlled by releasing and inhibiting hormones secreted from the hypothalamus. |
| 3. | It serves as the terminal end of the hypothalamo-hypophyseal tract. |

| 1. | adrenal | 2. | pineal |
| 3. | parathyroid | 4. | salivary |
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
| Assertion (A): | For steroid or thyroid hormones, their receptors are located inside the cell of the target cell. |
| Reason (R): | To bind their receptors, these hormones must first cross the cell membrane. |
In the light of the above statements choose the correct answer from the options given below:
| 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: PTH is involved in the regulation of phosphate levels in the body.
Reason: PTH increases the reabsorption of phosphate from the proximal tubule of the kidney.
1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false.
- If both the assertion and the reason are true and the reason is a correct explanation of the assertion
- If both the assertion and reason are true but the reason is not a correct explanation of the assertion
- If the assertion is true but the reason is false
- If both the assertion and reason are false
| Assertion (A): | Stress induces the secretion of cortisol in human body. |
| Reason (R): | Cortisol increases blood glucose level needed to combat stress. |
In the light of the above statements choose the correct answer from the options given below:
| 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. |
