Which one is a correct match

Options

A. Luteinising hormone- ovulation
B. Insulin - Diabetes insipidus
C. Parathormone - Diabetes mellitus
D. Thyroxine- Tetany.

Answer

To solve the question "Which one is a correct match?" we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Hormones and Their Functions**:
- We have four hormones to analyze: Luteinizing hormone, Insulin, Parathormone, and Thyroxine.
- We also have four conditions or diseases: Ovulation, Diabetes Insipidus, Diabetes Mellitus, and Tetany.

2. **Analyze Each Option**:
- **Luteinizing Hormone (LH) and Ovulation**:
- Luteinizing hormone is secreted by the anterior pituitary gland and plays a crucial role in triggering ovulation, which is the release of a mature egg from the ovary.
- **Conclusion**: This is a correct match.

- **Insulin and Diabetes Insipidus**:
- Insulin is secreted by the beta cells of the pancreas and is responsible for regulating blood glucose levels. A deficiency in insulin leads to Diabetes Mellitus, not Diabetes Insipidus.
- **Conclusion**: This is an incorrect match.

- **Parathormone and Diabetes Mellitus**:
- Parathormone (or parathyroid hormone) is secreted by the parathyroid glands and regulates calcium levels in the blood. A deficiency in parathormone can lead to tetany, while Diabetes Mellitus is caused by a deficiency of insulin.
- **Conclusion**: This is an incorrect match.

- **Thyroxine and Tetany**:
- Thyroxine is produced by the thyroid gland and is involved in regulating metabolism. A deficiency in thyroxine can lead to conditions like hypothyroidism, but not tetany. Tetany is caused by a deficiency of parathormone.
- **Conclusion**: This is an incorrect match.

3. **Final Conclusion**:
- The only correct match is **Luteinizing Hormone and Ovulation**.

### Answer:
The correct match is **Luteinizing Hormone - Ovulation**.
