The strength of ventricular contraction increases when SAN is stimulated by

Ventricular contraction in command of :-

neural signals through parasympathetic neural signals (another comonent of ANS) can a. Increase the heart beat rate b. Decrease the heart beat rate c. increase the strength of ventricular contraction e. Increase cardiac output f. Decreases cardiac output

neural signal through autonommic nervous system (ANS) can a. Increase the heart beat rate b. Decrease the heart beat rate c. Increase the strength of ventricular contraction d. Decrease the speed of conduction of action potential e. Increase cardiac output f. Decrease cardiac output

Ventricular contraction is in command of :-

Assertion : Neutral signals through sympathetic nerves can increase the strength of ventricular contraction Reason : Parasympathetic neutral signals synergistically act with sympathetic neutral signal to increase the cardiac output.
