Question
Explain the role of neural system in regulation of respiration.
Solution
There are various centres in the neural system that plays significant a role in the regulation and control of respiration.
Those are:
- Pneumotaxic centre: It is found in the pons varoli of the brain's dorsal portion (back). It shortens the length of inspiration and changes the pace of respiration.
- Respiratory Rhythm Centre or Medullary inspiratory Centre: It is present in the medulla of the brain. It regulates the respiratory rhythm.
- Apneustic centre: This is present in the lower part of the pons varoli of the brain. It increases the duration of inspiration.
- Chemosensitive centre: This is present in the medulla oblongata and the pons area of the brain.
