Question

Explain the role of neural system in regulation of respiration.

Answer 1

There are various centres in the neural system that plays significant a role in the regulation and control of respiration.

Those are:

1. 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.
2. Respiratory Rhythm Centre or Medullary inspiratory Centre: It is present in the medulla of the brain. It regulates the respiratory rhythm.
3. Apneustic centre: This is present in the lower part of the pons varoli of the brain. It increases the duration of inspiration.
4. Chemosensitive centre: This is present in the medulla oblongata and the pons area of the brain.
