Aus Dornheim Anatomy
The atrioventricular bundle, also known as the fasciculus atrioventricularis, AV bundle or His bundle, is a component of the heart's conduction system. It is 4 mm thick and 20 mm long. The AV bundle originates subendocardially in the atrium from the AV node. It penetrates the trigonum fibrosum dextrum and then divides into the two tawara legs in the pars membranacea of the ventricular septum. The function of the AV bundle is to transmit excitation from the AV node to the ventricular legs.
