In the conduction system of the heart, which of the following components is stimulated after the sinoatrial node?
Left bundle branch
Purkinje fibers
Right bundle branch
Atrioventricular node
The Correct Answer is D
A. Left bundle branch: The left bundle branch is stimulated after the atrioventricular node and bundle of His, not immediately after the sinoatrial node.
B. Purkinje fibers: The Purkinje fibers are stimulated later in the conduction pathway, after the bundle branches.
C. Right bundle branch: The right bundle branch is also stimulated after the atrioventricular node and bundle of His.
D. Atrioventricular node: After the sinoatrial node initiates the heartbeat, the electrical impulse travels to the atrioventricular node, which then passes the signal to the bundle of His and down to the bundle branches.
