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

Assertion : Neural signals through the sympathetic nerves can increase the rate of heart beat, the strength fo ventriculrar contraction and thereby the cardiac output. Reason : Adrenal medullary hormones can increase the cardiac output.

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