The correct Answer is:
To solve the question of which neural signal can reduce the duration of inspiration, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Process of Breathing**: - Breathing consists of two main processes: inspiration (inhaling) and expiration (exhaling). Inspiration is the process where air enters the lungs, and expiration is when air is expelled from the lungs. 2. **Identify the Centers that Regulate Breathing**: - The respiratory system is regulated by several centers in the brain. The primary centers involved are: - **Respiratory Rhythm Center**: Located in the medulla, it regulates the basic rhythm of breathing. - **Pneumotaxic Center**: Located in the pons, it helps regulate the rate and pattern of breathing. 3. **Focus on the Duration of Inspiration**: - The question specifically asks about reducing the duration of inspiration. This means we need to identify which center has the capability to shorten the inhalation phase. 4. **Analyze the Role of the Pneumotaxic Center**: - The pneumotaxic center has a direct influence on the respiratory rhythm center. When activated, it sends signals that can inhibit the inspiratory phase, thus reducing the duration of inspiration. 5. **Conclusion**: - The correct answer to the question is the **Pneumotaxic Center** (Option C), as it is responsible for reducing the duration of inspiration by sending neural signals to the respiratory rhythm center. ### Final Answer: The neural signal from the **Pneumotaxic Center** can reduce the duration of inspiration. ---

Assertion :- Pneumotaxic centre can moderate the functions of the respiratory rhythm centre. Reason :- Neural signal from pneumotoxic centre can reduce the duration of inspiration and thereby the alter the respiratory centre

Assertion (A) In brain stem, pons is called pneumotaxic centre with the ability to moderate the function of the ' respiratory rhythm' centre. Reason ( R) Neural signals from the centre can reduce the duration of expiration, thereby alter the respiratory rate

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 .

Assertion :- Strong pneumotoxic signal results complete filling of lungs. Reason :- Strong pneumotaxic singla increases the duration of inspiration as well as expiration.
