An oval mass of white mater . Present

Options

A. Pneumothoracic center
B. Pneumococcal center
C. Pneumatic center
D. Pneumotaxic center

Answer

To solve the question about the oval mass of white matter present in the brain, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure**: The question refers to an oval mass of white matter in the brain. The specific structure we are looking for is called the "Centrum Semiovale."

2. **Locate the Centrum Semiovale**: The Centrum Semiovale is located in the cerebral hemisphere of the brain. It is situated above the lateral ventricles and is primarily composed of myelinated axons, which gives it the white matter appearance.

3. **Function of the Centrum Semiovale**: This area plays a crucial role in the brain's functioning, particularly in the control of various activities. It is associated with the regulation of respiratory rhythm.

4. **Relation to the Pneumotaxic Center**: The Centrum Semiovale is closely related to the pneumotaxic center, which is responsible for controlling the rate and pattern of breathing. This center helps maintain the respiratory rhythm by regulating the transitions between inhalation and exhalation.

5. **Conclusion**: Based on the information gathered, the oval mass of white matter present in the brain is the "Centrum Semiovale," and it is primarily associated with the pneumotaxic center that regulates respiratory functions.

### Final Answer:
The oval mass of white matter present in the brain is the **Centrum Semiovale**, which is associated with the **Pneumotaxic Center** that controls respiratory rhythm.
