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.

What are the pathways through the body for electrical impulses?
in what order do the structures of the neuron carry the electrical signal?
What node is located in the inferior portion of the interatrail septum?
the AV node.
What is the most important structure of the human heart?
It is supposed to be the sinus node and the conducting tissue. It includes the AV node and bundle of HIS. The sinus node generate the impulse in the heart for contraction. The AV node and bundle of HIS transmits the impulse to the ventricles.
What is the correct sequence of cardiac electrical activity?
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
What areas of the cardiac conduction system make up the AV junction?
AV node and bundle of His
Correct order of intrinsic cardiac conduction?
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.
What if the av node malfunctions?
what are the causes of av node malfunction
The tertiary pacemaker is also known as the?
av node
The correct sequence in the conduction system of the heart is?
SA node, Internodal pathways, AV node, Bundle of His, Bundle branches, Purkinje fibers.
What size is the AV node?
AV ~1x3x5mm
What are the pathways through the body for electrical impulses?
in what order do the structures of the neuron carry the electrical signal?
Is AV NODE known as pacemaker?
No, it is the SAN (sinoatrial node)
What is AV nodal delay?
AV node is responsible for the delayin transmission of impulse generated in the SA node.This delay of impulse transmissions is called AV nodal delay. It is about 0.09 sec.Causes of AV nodal delayi. Junctional fibres of the AV node are very small in size.ii. Prolonged refractory periodof AV node.
What node is located in the inferior portion of the interatrail septum?
the AV node.
What is the correct path for the transmission of an impulse in the instrinsic condition system of the heart?
sinoatrial (SA) node, atrioventricular (AV) node, atrioventricular (AV) bundle, right and left bundle branches, Perkinje fibers
What is the correct sequence of parts that function to carry cardiac impulses?
SA node, AV node, AV Bundle, Purkinje Fibers
How are the contractions of the 4 chambers in the heart coordinated?
SA node and AV node
