Question

Human beings have a significant ability to maintain and moderate the respiratory rhythm to suit demands of the respiratory to suit demands of the body. For it we have

Respiratory rhythm centre in medulla - R

Pneumotaxic centre in pons - PT

Chemosensitive area in medulla - $C_{1}$

Peripheral chemoreceptors in aortic arch and carotid artery - $C_{2}$

Find out the correct path for regulations of respirations.

• A. $PT \rightarrow \underset{\underset{C_{1}}{\uparrow}}{R} \leftarrow C_{2}$
• B. $C_{2} \rightarrow R \rightarrow PT \rightarrow C_{1}$
• C. $C_{1} \rightarrow \underset{\underset{R}{\uparrow}}{PT} \rightarrow C_{2}$
• D. $PT \rightarrow \underset{\underset{R}{\uparrow}}{C_{2}} \rightarrow C_{1}$

Answer 1

Answer: (A)

$PT \rightarrow \underset{\underset{C_{1}}{\uparrow}}{R} \leftarrow C_{2}$
