Term
Pacemaker Cells
Definition
Cells of the sinoatrial node that set the pace of cardiac contraction.
Term
Sinoatrial (SA) Node
Definition
A small mass of specialized cardiac muscle fibers located in the posterior wall of the right atrium of the heart that acts as a pacemaker by generating at regular intervals the electric impulses of the heartbeat.
Term
Atrioventricular (AV) Node
Definition
A small mass of specialized cardiac muscle fibers, located in the wall of the right atrium of the heart, that receives heartbeat impulses from the sinoatrial node and directs them to the walls of the ventricles.
Term
Atrioventricular Bundle
Definition
A bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles causing them to contract
Term
Right Bundle Branches
Definition
A continuation of the atrioventricular bundle, which extends from the upper part of the intraventricular septum that transmits impulses to the right ventricle.
Term
Left Bundle Branches
Definition
A continuation of the atrioventricular bundle, which extends from the upper part of the intraventricular septum that transmits impulses to the left ventricle.
Term
Purkinje Fibers
Definition
Any of the specialized cardiac muscle fibers, part of the impulse-conducting network of the heart, that rapidly transmit impulses from the atrioventricular node to the ventricles.
Term
Left Coronary Artery
Definition
Supplies the left side of the heart with oxygenated blood from the pulmonary circuit.
Term

Definition
Term
Circumflex Artery
