The correct Answer is:
To determine the location of the specialized center called the respiratory rhythm center, we can analyze the options provided: 1. **Cerebellum**: The cerebellum, often referred to as the "little brain," is primarily involved in coordination, balance, and the maintenance of speech. It does not play a direct role in regulating respiration. 2. **Lower part of the brain**: This area includes the medulla oblongata, which is known to control cardiovascular and respiratory rhythms. The medulla oblongata is indeed responsible for the regulation of respiration, making this option a strong candidate. 3. **Top portion of the brainstem**: The top part of the brainstem contains the pons, which is involved in functions like swallowing and bladder control. It does not primarily regulate respiration. 4. **None of these**: This option suggests that the respiratory rhythm center is located outside the mentioned areas, which is incorrect based on our analysis. After evaluating all the options, the correct answer is: **The respiratory rhythm center is located in the lower part of the brain, specifically in the medulla oblongata.** ### Steps Summary: 1. Identify the function of the cerebellum. 2. Analyze the role of the lower part of the brain (medulla oblongata). 3. Examine the functions of the top portion of the brainstem (pons). 4. Eliminate the option "none of these." 5. Conclude that the respiratory rhythm center is located in the lower part of the brain.

In which of the following, is the respiratory rhythm center located to regulate the process of respiration

Fill up the blanks in the following paragraph by selecting the correct option. Human beings have a significant ability to maintain and moderate the respiratory rhythm to suti the demands of the body tissues. This is done by the neural system. A specialised centre present in the medulla region of the brain called overset((i))"_______" is primarily responsible for this regulation. Another centre present in the pons region of the brain called overset((ii))"_______" can moderate the functions of the repiratory rhytm cenre. Neutral signal from this cenre cen reduce the duration of overset((iii))"_______" and thereby alter the respiratory rate. A overset((iv))"_______" is situated adjacent to the rhythm centre which is highly sensitive to CO_(2) and hydrogen ions.
