Solution
The correct option is B Pneumotaxic centre
The Pneumotaxic centre is located in the superior part of pons (part of hindbrain). It helps to moderate the functions of the respiratory rhythm centre present in the medulla. It gives inhibitory signals for inspiration which prevents over expansion of the lungs.
The apneustic centre is located in the lower part of the pons. It helps in moderating the functions of the respiratory rhythm centre present in the medulla.
The medullary centre is also called the respiratory rhythm centre. It is primarily responsible for the regulation of the rate of breathing.
