Pneumotaxic Centre in the Brain
The pneumotaxic centre is a crucial component of the brain's respiratory control system, located specifically in the pons.
Function of the Pneumotaxic Centre
- The pneumotaxic centre regulates the rhythm of breathing by influencing the duration of inspiration.
- By shortening the time taken for inhalation, it helps maintain a balanced respiratory rate.
Location and Structure
- The pons is situated above the medulla and below the midbrain.
- It plays a vital role in relaying signals between different parts of the brain and is integral to the control of autonomic functions.
Interaction with Other Centres
- The pneumotaxic centre works in conjunction with the apneustic centre, which promotes prolonged inhalation.
- This balance between the two centres ensures efficient breathing patterns, adapting to the body's needs during various activities.
Importance in Respiratory Health
- Proper functioning of the pneumotaxic centre is essential for maintaining homeostasis in respiratory activities.
- Dysregulation can lead to breathing disorders, affecting overall health.
In conclusion, the correct answer is option 'C', the pons, as it houses the pneumotaxic centre that modulates the duration of inspiration, thereby affecting the respiratory rate. Understanding this mechanism is crucial for fields related to medicine and physiology, particularly in contexts like NEET preparations.

Option (c) is the correct answer as pneumotaxic centre is present in the pons region of the brain, that can moderate the functions of the respiratory rhythm centre.
Option (b) is incorrect as medulla oblongata possesses respiratory rhythm centre and a chemosensitive area.
Option (a) and (d) are incorrect as cerebrum and thalamus does not possess any specialised centre to moderate the respiratory rhythm to suit the demands of the body tissues.
