Hypersecretion of a hormone is responsible for the change of emotional state as fear, anger, pain and rise of blood pressure and heart rate. It is ?

Options

A. Insulin
B. Adrenaline
C. Progesterone
D. Thyroxine

Answer

To solve the question regarding which hormone's hypersecretion is responsible for changes in emotional states such as fear, anger, pain, and the rise of blood pressure and heart rate, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Hypersecretion**:
- Hypersecretion refers to the excessive secretion of a hormone in the body. This can lead to various physiological and emotional changes.

2. **Identifying the Hormones**:
- The question provides four options: insulin, adrenaline, progesterone, and thyroxine. We need to analyze each hormone's function and effects on the body.

3. **Analyzing Insulin**:
- Insulin is produced by the pancreas and primarily regulates glucose levels in the blood. It does not significantly influence emotional states or the physiological responses associated with fear or anger.

4. **Analyzing Adrenaline**:
- Adrenaline (also known as epinephrine) is secreted by the adrenal medulla. It is known as an emergency hormone that prepares the body for 'fight or flight' responses. It increases heart rate, blood pressure, and alertness, and is closely associated with emotional responses like fear and anger.

5. **Analyzing Progesterone**:
- Progesterone is produced by the ovaries and is primarily involved in the menstrual cycle and pregnancy. It does not have a direct role in acute emotional responses or in increasing heart rate and blood pressure.

6. **Analyzing Thyroxine**:
- Thyroxine (T4) is produced by the thyroid gland and regulates metabolism. While it can affect energy levels and metabolism, it is not directly linked to immediate emotional changes or the acute stress response.

7. **Conclusion**:
- Based on the analysis, the hormone responsible for the changes in emotional state such as fear, anger, pain, and the rise in blood pressure and heart rate due to hypersecretion is **Adrenaline**.

### Final Answer:
The correct answer is **Adrenaline**.
