Excess of growth hormone causes acromegaly in adults . In normal individuals, such condition doesn't arise due to inhibition of growth hormone . Which of the following is responsible for secretion of hormone that regulates growth hormone secretion ?

Options

A. The gland situated at the base of diencephalon
B. The gland situated in a bony cavity of the sphenoid bone
C. The gland situated on the dorsal side of the forebrain
D. The gland having two lobes situated on either side of the trachea

Answer

To solve the question regarding which gland is responsible for the secretion of the hormone that regulates growth hormone secretion, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the gland that is responsible for the secretion of a hormone that regulates growth hormone secretion. It is important to differentiate between the gland that secretes growth hormone and the one that regulates its secretion.

2. **Identifying the Glands**:
- **Hypothalamus**: This gland is located at the base of the diencephalon and is responsible for producing hormones that regulate the secretion of other hormones, including growth hormone.
- **Pituitary Gland**: This gland is located in the sphenoid bone and secretes growth hormone but is not responsible for regulating its secretion.
- **Pineal Gland**: Located on the dorsal side of the forebrain, it secretes melatonin and does not regulate growth hormone.
- **Thyroid Gland**: Located on either side of the trachea, it secretes thyroxine and is not involved in the regulation of growth hormone.

3. **Analyzing the Options**:
- **Option 1**: Gland situated at the base of the diencephalon (Hypothalamus) - This is the correct answer as it regulates growth hormone secretion.
- **Option 2**: Gland situated in the bone cavity of the sphenoid bone (Pituitary Gland) - This is incorrect as it secretes growth hormone but does not regulate it.
- **Option 3**: Gland situated on the dorsal side of the forebrain (Pineal Gland) - This is incorrect as it secretes melatonin.
- **Option 4**: Gland having two lobes situated on either side of the trachea (Thyroid Gland) - This is incorrect as it secretes thyroxine.

4. **Conclusion**: The gland responsible for the secretion of the hormone that regulates growth hormone secretion is the **Hypothalamus**.

### Final Answer:
The correct answer is **Option 1: Gland situated at the base of the diencephalon (Hypothalamus)**.
