If thymectomy is done during old age then what possibility is there?

Options

A. Suppress immune system
B. Die immediately
C. No adverse reaction
D. Myasthenia gravis

Answer

To answer the question, "If thymectomy is done during old age, then what possibility is there?", we can follow these steps:

### Step 1: Understand Thymectomy
Thymectomy is the surgical removal of the thymus gland. The thymus is an important organ in the immune system, particularly in the development and differentiation of T-cells, which are crucial for cell-mediated immunity.

**Hint:** Recall that the thymus gland plays a significant role in immune function, particularly in young individuals.

### Step 2: Consider the Function of the Thymus in Old Age
In older individuals, the thymus gland undergoes a process of degeneration, which means its size and function decrease over time. This leads to a natural decline in immune response as people age.

**Hint:** Think about how aging affects the immune system and the role of the thymus in that process.

### Step 3: Analyze the Effects of Thymectomy in Older Adults
Since the thymus is already degenerating in older adults, removing it (thymectomy) may not have severe consequences. The immune system is already weakened due to age, and the removal of the thymus may not lead to immediate adverse reactions.

**Hint:** Consider the state of the immune system in elderly individuals and how it might respond to the removal of the thymus.

### Step 4: Evaluate Possible Outcomes
- **Suppress immune system:** While the immune system is already weakened, thymectomy may not significantly suppress it further.
- **Die immediately:** This is unlikely; the body can adapt to the absence of the thymus, especially in older individuals.
- **No adverse reaction:** This is a plausible outcome since the thymus is already not functioning optimally.
- **Myasthenia Gravis:** This is an autoimmune disorder that may be associated with thymus issues but is not a direct consequence of thymectomy in older adults.

**Hint:** Weigh the likelihood of each outcome based on the current state of the thymus in older individuals.

### Step 5: Conclusion
The most likely possibility if thymectomy is done during old age is that there will be **no adverse reaction**. The immune system may remain suppressed, but this is not a direct result of the surgery, as the immune response is already compromised due to aging.

**Final Answer:** The correct possibility is that there will be no adverse reaction.
