The correct Answer is:
To solve the question regarding the "oval mass of white matter present," we will analyze the options provided and identify the correct answer step by step. ### Step-by-Step Solution: 1. **Understanding the Question**: The question refers to an "oval mass of white matter." In the context of neuroanatomy, white matter consists of myelinated axons that connect different parts of the brain. 2. **Identifying the Options**: The options given are: - A) Pneumothoracic center - B) Pneumococcal center - C) Pneumatic center - D) Pneumotactic center 3. **Analyzing Each Option**: - **Pneumothoracic Center**: This term is not commonly used in neuroanatomy and refers more to the thoracic cavity. It is likely incorrect in this context. - **Pneumococcal Center**: This term relates to a type of bacteria (Streptococcus pneumoniae) and is not relevant to the structure of the brain. - **Pneumatic Center**: While this term does relate to the brain, it typically refers to functions associated with respiration but does not specifically refer to an oval mass of white matter. - **Pneumotactic Center**: This is a center in the brain that regulates the rate and rhythm of breathing. It is located in the pons and is associated with the presence of white matter. 4. **Identifying the Correct Answer**: The correct answer is **D) Pneumotactic center**. The pneumotactic center is indeed an oval mass of white matter located in the brain, specifically in the cerebral hemisphere, and is responsible for controlling respiratory rhythm. ### Final Answer: The correct answer is **D) Pneumotactic center**.
