The disproportionate growth of bones of body parts due to the over secretion of GH after adolescene is known as

Options

A. Gigantism
B. Acromegaly
C. Dwarfism
D. None of these

Answer

To solve the question about the disproportionate growth of bones in body parts due to the over secretion of growth hormone (GH) after adolescence, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of Growth Hormone (GH)**:
- Growth hormone is produced by the pituitary gland and is responsible for growth and development in the body. It stimulates growth in tissues and bones.

2. **Identify the Timing of GH Secretion**:
- The question specifies that the over secretion of GH occurs after adolescence. This is a crucial detail because the effects of GH depend on the timing of its secretion.

3. **Differentiate Between Conditions**:
- **Gigantism**: This condition occurs when there is an over secretion of GH before the closure of growth plates in bones, typically during childhood or adolescence. It leads to excessive growth in height.
- **Acromegaly**: This condition occurs when there is an over secretion of GH after the growth plates have closed, which typically happens after adolescence. It results in the enlargement of bones and tissues, particularly in the hands, feet, and face.
- **Dwarfism**: This condition is characterized by insufficient GH secretion during childhood, leading to shorter stature.
- **None of these**: This option is not applicable as we have identified a relevant condition.

4. **Apply the Information**:
- Since the question specifies that the over secretion of GH occurs after adolescence, we can conclude that the correct term for this condition is **acromegaly**.

5. **Final Answer**:
- The disproportionate growth of bones of body parts due to the over secretion of GH after adolescence is known as **acromegaly**.
