Biology - Breathing and Exchange of Gases Question with Solution | TestHub
Given below are two statements.
Statement I - Apneustic centre controls slow wave sleep and rapid eye movement sleep.
Statement II - Pneumotaxic centre controls non-rapid eye movement sleep and wakefulness.
In the light of above statements, select the correct option given below:
Options:
Answer:
Solution:
The apneustic and pneumotaxic centres are located in the pons region of the hindbrain and are primarily responsible for the regulation of respiration.
The apneustic centre promotes inspiration by stimulating the inspiratory neurons in the medulla, whereas the pneumotaxic centre limits the duration of inspiration by sending inhibitory signals.
Sleep and wakefulness are primarily controlled by the reticular activating system (RAS), hypothalamus, and other associated brain regions, not by the respiratory centres.
Therefore, both Statement I and Statement II are incorrect.
Answer: Both statement I and statement II are incorrect.
