The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks which specialized center in the brain can reduce the inspiratory duration upon stimulation. 2. **Identifying the Centers**: The respiratory process is regulated by three main centers in the brain: - Medullary (or Medulla) Inspiratory Center - Pneumotaxic Center - Apneustic Center 3. **Function of Each Center**: - **Medullary Inspiratory Center**: This center controls the basic rhythm of breathing, including both inspiration and expiration. - **Pneumotaxic Center**: This center regulates the medullary inspiratory center and controls the pattern and rate of breathing. It specifically reduces the duration of inspiration, preventing overfilling of the lungs. - **Apneustic Center**: This center promotes prolonged inspiration and can lead to an increase in the duration of inspiration. 4. **Conclusion**: Among the centers mentioned, the **Pneumotaxic Center** is the one that reduces the inspiratory duration upon stimulation. 5. **Final Answer**: The correct answer is the **Pneumotaxic Center**. ---

Give the biological terms for each of the following: The principal heat regulating centre in the brain.

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.

Which of the following statements are CORRECT ? I. A specialized center present in the medulla region of the brain called respiratory rhythm center is primarily responsible for the regulation of respiration. II. A Chemosensitive area is situated adjacent to the rhythm which is highly sensitive to O_2,CO_2 and hydrogen ions . III . Receptors associated with aortic arch and carotid artery also can recognize changes in CO_2 and H^+ concentration and send necessary signals to the rhythm center for remedial actions. IV The neural signal from the pneumatic center can increase the duration of inspiration and thereby alter the respiratory rate .

The following combination are concerned with experiments of the characterization and use of a moving coil galvanometer. The series combination of variab resistance R, one 100 Omega resistor and moving coil galvanometer is connected to a mobile phone charger having negligible internal resistance. The zero of the galvanometer lies the centre and the pointer can move 30 division full scale on either side depending on the directin of current. The reading of the galvanometer is 10 divisions and the voltages across the galvanometer and 100 Omega resistor are respectively 12mV and 16 mV. The series combination of the galvanometer with a resistnce of R is conneted across an ideal voltage supply of 12 V and this time the galvanometer shows full scale defiention of 30 divisions. The value of R is nearly
