Spontaneous respiration ceases after transection of the
1 Brainstem above the pons
2 Spinal cord below the diaphragm
3 Brainstem at the inferior end of the medulla
4 Spinal cord above the conus medullaris
Explanation:
Respiratory centres are present in medulla oblongata (respiratory rhythm centre) and pons (pneumotaxic centre and apneustic centre). If brain is transected (cut across) below the medulla oblongata, impulses from the respiratory centre cannot reach the respiratory muscles.

Increase in \(\mathrm{CO}_{2}\) concentration shall cause
1 Slower and shallower breathing
2 Faster and deeper breathing
3 Slower and deeper breathing
4 No effect on breathing
Explanation:
Increase in \(\mathrm{CO}_{2}\) concentration shall cause faster and deeper breathing.

Respiratory process is regulated by certain specialized centres in the brain. One of the following listed centres can reduce the duration of inspiration upon stimulation
1 Medullary inspiratory centre
2 Pneumotaxic centre
3 Apneustic centre
4 Chemosensitive centre
Explanation:
Respiratory process is regulated by certain specialized centres in the brain. Pneumotaxic centres can reduce the duration of inspiration upon stimulation.
