| Question | Answer |
|---|---|
| Sinoatrial node (SA): | located in the right atrium near the superior vena cava and is the primary pacemaker of the heart. |
| Atrioventricular node (AV): | or junctional node is located in the inferior wall of the right atrium close to the tricuspid valve. |
| Bundle of His: | a group of fibers that initiates at the atrioventricular node, enters the interventricular system, and splits into the left and right ventricles. The fibers branch into small Purkinje fibers. |
| Purkinje fibers | compose the last part of the electrical conduction system of the heart. The fibers relay the electrical impulses to the muscle cells of the heart. |
