Read the following statements. Statement -A : Giagantism and acromicria are both caused due to over secretion of growth hormone. Statement-B : Gigantism occurs due to overactivity of pituitary before puberty while acromocria occurs due to pituitary hyposecretion after pubrty. Choose the correct option.

Options

A. Both statements are incorrect
B. Only statement A is incorrect
C. Only statement B is incorrect
D. Both statements are correct.

Answer

To solve the question, we need to analyze both statements provided:

**Statement A:** "Gigantism and acromegaly are both caused due to over secretion of growth hormone."

1. **Understanding Gigantism and Acromegaly:**
- Gigantism occurs when there is an overproduction of growth hormone before the growth plates close (before puberty). This results in excessive growth in height.
- Acromegaly occurs when there is an overproduction of growth hormone after the growth plates have closed (after puberty). This leads to the enlargement of bones and tissues, particularly in the hands, feet, and face.

2. **Conclusion for Statement A:**
- Since both conditions are indeed caused by the over secretion of growth hormone, **Statement A is true**.

---

**Statement B:** "Gigantism occurs due to overactivity of pituitary before puberty while acromegaly occurs due to pituitary hyposecretion after puberty."

1. **Analyzing the Conditions:**
- As established, gigantism is due to overactivity (hypersecretion) of the pituitary gland before puberty.
- However, acromegaly is not due to hyposecretion; it is due to hypersecretion of growth hormone after puberty.

2. **Conclusion for Statement B:**
- The part about acromegaly being caused by hyposecretion is incorrect. Therefore, **Statement B is false**.

---

**Final Conclusion:**
- Statement A is true.
- Statement B is false.
- The correct option is that only Statement B is incorrect.
