In the conduction system of the heart, which of the following components is stimulated after the sinoatrial node?
Understand the Problem
The question is asking which component of the heart's conduction system is activated following the sinoatrial node. This pertains to the sequence of electrical conduction in the heart.
Answer
Atrioventricular node
The next component stimulated after the sinoatrial node is the atrioventricular node.
Answer for screen readers
The next component stimulated after the sinoatrial node is the atrioventricular node.
More Information
The electrical impulse travels from the sinoatrial node to the atrioventricular node, allowing the heart's conduction system to efficiently coordinate the heartbeat.
Tips
A common mistake is confusing the sequence of conduction. It's important to remember the specific order of activation.
