Parathormone induces

Options

A. Increase in blood sugar level
B. Decrease in serum calcium level
C. Increase in serum calcium level
D. Decrease in blood sugar level

Answer

**Step-by-Step Solution:**

1. **Identify the Hormone**: The question asks about parathormone, which is also known as parathyroid hormone (PTH). It is secreted by the parathyroid glands.

2. **Understand the Function of Parathormone**: Parathormone plays a crucial role in regulating calcium levels in the body. Its primary function is to maintain calcium homeostasis.

3. **Determine the Effect of Parathormone**: When the calcium levels in the blood decrease, parathormone is released to increase the serum calcium levels. This is achieved through several mechanisms:
- It stimulates the release of calcium from bones.
- It enhances the reabsorption of calcium in the kidneys.
- It promotes the activation of vitamin D, which increases intestinal absorption of calcium.

4. **Analyze the Options**: The options provided are:
- Increases the blood sugar level
- Decreases the serum calcium level
- Increases the serum calcium level
- Decreases in the blood sugar level

5. **Select the Correct Answer**: Based on the function of parathormone, the correct answer is "increases the serum calcium level."

**Final Answer**: Parathormone induces an increase in the serum calcium level.
