339389 Assertion :
SAN initiates the heart rate
Reason :
Sympathetic nerve fibres increase the cardiac activity.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
BIOXI18: BODY FLUIDS AND CIRCULATION

339390 All the components of the conducting system of the heart can generate action potentials for the contraction of myocardium, but the sinoatrial node (SA node) acts as the pacemaker because

1 SA node conducts action potentials faster than any other part of the nodal system
2 Only the SA node is auto-excitable and autorhythmic but not AV node
3 The SA node is located in the atria whereas \(\mathrm{AV}\) node is located in the ventricles
4 The rate of rhythmic discharge of depolarisation is faster in SA node than in any other part of the nodal system
