SA node, Internodal pathways, AV node, Bundle of His, Bundle branches, Purkinje fibers.
Internal pacemaker , sinoatrial(sa) node, atrioventricular (av) node , atrioventricular bundle (bundle of his ) and purkinje fibres.
SA node- AV node- Bundle of His- Purkinje fibers
S-A node, A-V node, A-V bundle, Purkinje fibers
SA node, AV node, AV Bundle, Purkinje Fibers
Bundle of Hisatrioventicular bundle (bundle of his), right and left bundle bramches and the purkinge conducition fibers
Purkinje fibers.
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.
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
His bundle? or the Purkinje fibers?
1. SA Node ----> 2. AV Node---> 3. AV Bundle (bundle of HIS)----> 4. Purkinje Fibers
Av bundle
