Q. Humans have to maintain the moderate respiratory rhythms to suit the demands of the body. For fulfilling that purpose, we have the Respiratory rhythm centre in medualla = R Pneumotaxic centre in pons = PT Chemosensitive area in medulla = $C_{1}$ Peripheral chemoreceptors in aortic arch and carotid artery = $C_{2}$ Select the correct path for the regulation of respiration
A) $C_{1} \rightarrow PT\ \rightarrow C_{2}$ $\uparrow$ R
B) $PT \rightarrow C_{2}\ \rightarrow C_{1}$ $\uparrow$ R
C) $PT \rightarrow R\ \rightarrow C_{2}$ $\uparrow$ $C_{1}$
D) $C_{2} \rightarrow R \rightarrow PT \rightarrow \ C_{1}$
Explanation
Brain Part Control/Function Cerebellum – Coordination of muscular movement Cerebrum – Voluntary function Medulla oblongata – Respiration Hypothalamus – Temperature
