Explain the role of neural system

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, Respiratory Rhythm centre or Medullary inspiratory centre, Apneustic centre and chemosensitive centre.

1. Pneumotaxic centre:

It is present in the dorsal part (back) of the pons varoli of the brain. It decreases the time duration of the inspiration and alter the respiration rate.

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 is present in the lower part of the pons varoli of the brain. It increases the duration of inspiration.

4. Chemosensitive centre is present in the medulla oblongata and the pons area of the brain.
