The respiratory centre, which regulates respiration, is located in
1 cerebral peduncle
2 vagus nerve
3 pons varolii
4 medulla oblongata
Explanation:
(d) Respiratory centers that regulate respiration are located in medulla oblongata. Respiratory centre regulates normal breathing and also automatically adjusts the breathing rate to varying requirements of body during stress conditions.

The pneumotaxic centre that can moderate the function of respiratory rhythm centre is located in
1 dorsal side of medulla
2 ventral side of medulla
3 aortic arch and carotid artery
4 pons varolii
Explanation:
(d) Pneumotaxic center controls medullary respiratory centres, particularly inspiratory centre, so that duration of inspiration is controlled. It is located in pons varolii of brain.

Respiratory process is regulated by certain specialised centres in the brain. One of the following listed centres can reduce the inspiratory duration upon stimulation.
1 Medullary inspiratory centre
2 Pneumotaxic centre
3 Apneustic centre
4 Chemosensitive centre
Explanation:
(b) Pneumotaxic centre is located in the dorsal part of pons varolii of the brain. It can reduce the duration of inspiration and thus alter the respiratory rate.
Apneustic centre responsible for promoting inspiration process is located in the lower part of pons varoli.
Chemosensitive centre which is highly sensitive to $\text{C}{{\text{O}}_{2}}$ and hydrogen ions is situated adjacent to the rhythm centre. Increase in $\text{C}{{\text{O}}_{2}}$ and ${{\text{H}}^{+}}$in body activates this centre for the elimination of $\text{C}{{\text{O}}_{2}}$ and $\text{H}$.
Medullary inspiratory centre is a specialised region present in the medulla of the brain, and is primarily responsible for regulating the respiratory rhythm.
