Neural signal from which centre can reduce the duration of inspiration is

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

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 .

Which centre controls the switch off point of inspiration?

Strong neural signals from the pneumotaxic centre 1) increase the respiratory axis 2) increase the duration of respiration 3) Decrease the duration of respiration 4) Both 1 and 2

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