The correct Answer is:
To solve the question regarding which specialized center in the brain can reduce the inspiratory duration upon stimulation, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: The question asks which center in the brain regulates the respiratory process by reducing the duration of inspiration. 2. **Identify the Respiratory Centers**: The main respiratory centers in the brain include: - Medullary Inspiratory Center - Pneumotaxic Center - Apneustic Center - Chemosensitive Center 3. **Analyze Each Center**: - **Medullary Inspiratory Center**: Located in the medulla, it primarily regulates the rhythm of breathing but does not specifically reduce the duration of inspiration. - **Pneumotaxic Center**: Located in the dorsal part of the pons, this center is responsible for regulating the rate of breathing by reducing the duration of inspiration. - **Apneustic Center**: Found in the lower part of the pons, it promotes inspiration rather than reducing it. - **Chemosensitive Center**: This center is sensitive to CO2 and hydrogen ions and plays a role in the regulation of breathing but does not directly reduce inspiratory duration. 4. **Conclusion**: Based on the analysis, the center that reduces the inspiratory duration upon stimulation is the **Pneumotaxic Center**. ### Final Answer: The correct answer is the **Pneumotaxic Center**. ---

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
