In man removal of Parathyroid gland leads to:

Options

A. Acromegaly
B. Tetany
C. Polyuria
D. Diabetes insipidus

Answer

### Step-by-Step Solution:

1. **Understanding the Role of the Parathyroid Gland**:
- The parathyroid glands are small glands located behind the thyroid gland. They are responsible for producing parathyroid hormone (PTH), which regulates calcium levels in the blood.

2. **Effects of Parathyroid Hormone (PTH)**:
- PTH increases blood calcium levels by stimulating the release of calcium from bones, increasing calcium absorption in the intestines, and promoting calcium reabsorption in the kidneys.

3. **Consequences of Parathyroid Gland Removal**:
- Removal of the parathyroid glands leads to a decrease in PTH levels, resulting in lower blood calcium levels (hypocalcemia).

4. **Identifying Symptoms of Hypocalcemia**:
- Low calcium levels can lead to various symptoms, including:
- **Tetany**: This is characterized by muscle spasms and cramps due to increased excitability of nerves and muscles.
- **Polyuria**: This refers to excessive urination, which can occur due to hormonal imbalances affecting kidney function.

5. **Clarifying Other Conditions**:
- The mention of acromegaly is incorrect in this context as it is related to excess growth hormone, not the removal of the parathyroid gland.
- Diabetes and encephalitis are also not directly related to the removal of the parathyroid gland.

6. **Conclusion**:
- The primary conditions that arise from the removal of the parathyroid gland are **tetany** and **polyuria** due to the resultant hypocalcemia.

### Final Answer:
Removal of the parathyroid gland leads to **tetany** and **polyuria** due to decreased levels of parathyroid hormone and resultant hypocalcemia.
