Question

The respiratory mechanism is controlled by the

• A. parasympathetic nervous system
• B. sympathetic nervous system
• C. central nervous system
• D. peripheral nervous system

Answer 1

The correct option is C central nervous system

The respiratory centers that control your rate of breathing are in the brainstem or medulla. Involuntary respiration is controlled by the respiratory centers of the upper brainstem and the pons located underneath the medulla controls the rate or speed of involuntary respiration. The medulla oblongata helps send signals to the muscles that control respiration to cause breathing to occur and thereby controls voluntary respiration. Thus, both the voluntary and involuntary respiratory mechanisms are controlled by the central nervous system. So, the correct option is 'Central nervous system'.
