The only path of conduction for impulse transmission from the atria to the ventricles through the AV node and AV bundle because the atria and ventricles are insulated from each other due to the fibrous skeleton present in the heart.
Impulse transmission is the transfer of electric signals from the brain to the rest of the body or vice-versa. These transmissions are also conducted inside the heart to mediate the contraction and relaxation of the heart cardiac muscles.
AV node is the atrioventricular node that is located on the interatrial septum. The function of AV node is to act as a gatekeeper and delay the excitation between the atria and ventricles.
