there is the junctional node, the bundle of his and the left and right bundle branches
There are two bundle branches, right and left.
SA node, Internodal pathways, AV node, Bundle of His, Bundle branches, Purkinje fibers.
Nerve impulses come through the sinus node of the heart to the bundle of His and then move into the right and left bundle branches.
SA node, AV node, AV Bundle, Bundle branches, subedocardial branches (purkinje fibers)
bundle branches
within the interventricular septum
To transfer electrical activity to pakinji mucsles
sinoatrial (SA) node, atrioventricular (AV) node, atrioventricular (AV) bundle, right and left bundle branches, Perkinje 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.
This si known as a Bundle Branch Block - and refers to an anomaly of a blockage in the nerve system of the heart at the bundle branches.
The right bundle carries nerve impulses that cause contraction of the right ventricle (the lower chamber of the heart) and the left bundle carries nerve impulses that cause contraction of the left ventricle.
