AV node and bundle of His
Its one of these, cant remember which one though: AV node, SA node AV bundle, Purkinje fibres. SA node, AV bundle, Purkinje fibres, AV node. SA node, AV node, AV bundle, Purkinje fibres. Purkinje fibres, SA node, AV node, AV bundle.
SA node, AV node, AV Bundle, Purkinje Fibers
SA node, Internodal pathways, AV node, Bundle of His, Bundle branches, Purkinje fibers.
The impulses from SA node spread through out the atrial musculature in about 0.09 seconds, and parallel to it, the impulses also reach the AV node. From AV node, after a delay of about 0.12 seconds they pass to the inter ventricular septum through the Bundle of His, which soon divides into Left and Right Bundle branch and ultimately into the Purkinje fibers which first depolarize the endocardium of the ventricles and then the rest of ventricular musculature. SA Node --> Atria, AV node --> Bundle of His --> Right & Left Bundle Branches --> Purkinje fibers
sinoatrial (SA) node, atrioventricular (AV) node, atrioventricular (AV) bundle, right and left bundle branches, Perkinje fibers
You have the specialized conduction tissue called as bundle of His. This bundle spread across the inter ventricular septum to cover the walls of both the ventricles. The bundle was named after the name of God, so the name goes as bundle of His. These cells get depolarized immediately after the the AV node.
The cardiac conduction tissues in the human heart comprise specialized myocytes that can be differentiated from working myocardium with routine histological staining. They are located in specific regions of the heart to form the sinus node and the atrioventricular (AV) node, which then extend into the AV bundle and bundle branches
in what order do the structures of the neuron carry the electrical signal?
Internal pacemaker , sinoatrial(sa) node, atrioventricular (av) node , atrioventricular bundle (bundle of his ) and purkinje fibres.
Av bundle
AV valves close during the systole phase of the cardiac cycle.
