Neural signals through sympathetic nerves can:-

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.

Decrease in the rate of heart beat, speed of conduction of action potential and thereby the cardiac output is under the control of

Which of the following statement is CORRECT ? I. Heart, the mesodermally derived organ, is situated in the thoracic cavity, in between the two lungs , slightly tilted to the left. II. During joint diastole , tricuspid and bicuspid valves are open and the semilunar values are closed. III. The first heart sound (lub) is associated with the closure of the tricuspid and biscuspid valves whereas the second heart sound (dub) is associated with the closure of the semilunar valves . IV. Neural signals through the sympathetic nerves can increases the rate of hearbeat, the strength of ventricular contraction and thereby the cardiac output.
