the bundle of modified cardiac muscle fibers that begins at the atrioventricular node as the trunk of the atrioventricular bundle and passes through the right atrioventricular fibrous ring to the membranous part of the interventricular septum where the trunk divides into two branches, the right bundle [TA] (crus dextrum [TA]) of the atrioventricular bundle and the left bundle [TA] (crus sinistrum [TA]) of the atrioventricular bundle; the two crura ramify in the subendocardium of their respective ventricles.

bundle of HisA bundle of specialised cardiac muscle fibres which carries the electric impulses for the co-ordinated contraction of the heart. The bundle begins at the AV node located at the inferior interatrial septum, and passes into the subendocardium through the right fibrous trigone to the interventricular septum, after which it divides into right and left limbs that pass along either side of the septum, branching to the walls of the ventricles.
