The respiratory rhythm centre is in Medulla is primarily responsible for this regulation.
Following respiratory group regulate respiration:
1) The Dorsal Respiratory Group - The nervous signal released from this group is transmitted to the diaphragm and EICM.
2) The Ventral Respiratory Group - During normal respiration, this remains inactive and even does not play any role. In the enhanced respiratory drive, the respiratory signal of this group contribute to fullfill the demand by regulating both inspiration and expiration.
3) The Pneumotaxic Centre - Located dorsally in the upper pons and also know as switch off point of inspiration. when this signal is strong, the inspiration lasts for a shorter duration and lungs are filled partially respiration rhythm centre.
Neural signal from this centre can reduce the duration of inspiration and thereby alter the respiratory rate.
