a characteristic of conduction
What is the sinoatrial (SA) node?
group of muscle cells in the heart that generate electrical impulses that control the heart’s rhythm and rate

Bundle branches
Bundle of His
AV node
interatrial and internodal pathways

Refractory Period refers to the time during which a nerve or muscle is unresponsive to further stimulation.

The time during which a nerve or muscle is contracting
Where does the SA node reside?
In the left atrium
In the right atrium
In the left ventricle
In the right ventricle
Bundle of His
extend from the AV node
transmits electrical impulses to the ventricles' Purkinje fibers

continue as the bundle branches; located in the interventricular septum, which separates the heart's left and right ventricles
How does an electrical current travel through the heart?
conduction pathway
SA node initiates the sequence → atria contract → electrical current then travels through the AV node → bundle of His → bundle branches → Purkinje fibers → ventricles contract
