The thick fibers extending from the AV node are known as the bundle of His, or atrioventricular bundle. This structure conducts electrical impulses from the AV node to the ventricles, facilitating coordinated heart contractions. The bundle of His branches into the right and left bundle branches, which further spread the electrical signals throughout the ventricles via Purkinje fibers. This conduction system is essential for maintaining an effective heartbeat.

in what order do the structures of the neuron carry the electrical signal?
Av bundle
SA node, AV node, AV Bundle, Purkinje Fibers
The impulse starts in the right atria in the sinus node, then travels through the intratrial fibers for atrial contraction, then travels down to the the av node where it is delayed, then travels down through the bundle branches to the purkinjee fibers to the ventricular myocardium for contraction.
Electricity fires from the SA node to the AV node. It then goes to the bundle of his and out the perkinji fibers.

No, the sinoatrial (SA) node initiates contraction of the atria, which subsequently causes stimulation of the AV node, which then initiates contraction of the ventricles via the Purkinje fibers.
