A specialised centre known as respiratory rhythm
centre regulates respiration. It is located in

Options

A. Pons
B. Medulla oblongata
C. Cerebrum
D. Cerebellum

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the location of a specialized center known as the respiratory rhythm center, which regulates respiration.

2. **Identifying the Role of the Respiratory Rhythm Center**: The respiratory rhythm center is responsible for maintaining and moderating the rhythm of breathing in humans.

3. **Central Nervous System Involvement**: The regulation of respiration is primarily controlled by the central nervous system, specifically by two areas: the pons and the medulla oblongata.

4. **Locating the Respiratory Rhythm Center**: The respiratory rhythm center is specifically located in the medulla oblongata. This is the main center that regulates the rhythm of respiration.

5. **Understanding Related Centers**: There is also a pneumotactic center located in the pons, which can influence the activities of the respiratory rhythm center by stimulating or inhibiting it.

6. **Conclusion**: Based on the information, the correct answer to the question is that the respiratory rhythm center is located in the medulla oblongata.

**Final Answer**: The respiratory rhythm center is located in the medulla oblongata.
