Parasympathetic neural signals

Vedclass · Answer

(C) Option $(C)$ is the correct answer.Parasympathetic neural signals decrease the rate of heartbeat,the speed of conduction of action potentials,and the stroke volume,thereby decreasing the cardiac output.Adrenal medullary hormones increase cardiac output.Sympathetic neural signals increase the rate of heartbeat,the strength of ventricular contraction,and thereby the cardiac output.The pneumotaxic centre is involved in the regulation of respiration,not cardiac activity.

Which of the following is associated with a decrease in cardiac output?
