BIOXI17: BREATHING AND EXCHANGE OF GASES
338792
Pneumotaxic centre of the brain, i.e. pons region can
1 Moderate the function of respiratory system directly
2 Decrease the heart rate
3 Increase the heart rate
4 Moderate the function of respiratory rhythm centre
Explanation:
Respiratory centre present in the pons region of the brain is called pneumotaxic centre. It can moderate the functions of respiratory rhythm centre.
BIOXI17: BREATHING AND EXCHANGE OF GASES
338793
Respiratory centre of brain is situated in
1 Cerebrum
2 Medulla oblongata
3 Hypothalamus
4 Cerebellum
Explanation:
Respiratory centres is situated in medulla oblongata.

338794
In response to \(\mathrm{CO}_{2}\) and \(\mathrm{H}^{+}\)concentration, the chemosensitive area and the receptors associated with aortic arch and carotid artery, send necessary singnals for remedial actions to
1 Pneumotaxic centre
2 Respiratory rhythm centre
3 Apneumotaxic centre
4 Both (1) and (2)
Explanation:
In response to \(\mathrm{CO}_{2}\) and \(\mathrm{H}^{+}\)concentration, the chemosensitive area and, receptors associated with aortic arch and carotid artery, send necessary signals for remedial action to respiratory rhythm centre.
BIOXI17: BREATHING AND EXCHANGE OF GASES
338795
Which of the following is incorrect regarding respiration :-
1 Role of \(\mathrm{O}_{2}\) is significant
2 Chemoreceptors present in aortic arch and carotid artery can detect the change of \(\mathrm{CO}_{2}\) in blood
3 Herring bruer reflex prevents over dilation of lungs
4 Pneumotaxic centre is present in Pons
Explanation:
Herring Bruer reflex is a reflex that will prevent over inflation of lungs. Herring Bruer reflex is initiated by expansion of lungs which in turn excites stretch receptors. Stimulation of stretch receptors will send signals to medulla of brain to shorten inspiratory time.
