Regulation of Respiration
BIOXI17: BREATHING AND EXCHANGE OF GASES

338783 Statement A :
A specialised centre present in the medulla region of the brain called pneumotaxic centre is primarily responsible for this regulation.
Statement B :
Another centre present in the pons region of the brain called respiratory rhythm centre can moderate the functions of the previous centre.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
BIOXI17: BREATHING AND EXCHANGE OF GASES

338784 Consider the following statements.
I. Neural signals from pneumotaxic centre can reduce the duration of expiration and thus, alter the respiratory rate.
II. The role of oxygen in the regulation of respiratory rhythm is quite insignificant.
Select the correct option.

1 I is false, II is true
2 Both I and II are true
3 I is true, II is false
4 Both I and II are false

338785 Respiratory rhythm is primarily controlled by

1 Central nervous system
2 Sympathetic nervous system
3 Parasympathetic nervous system
4 Autonomic nervous system
