Bundle of parallel myofilaments
WebIn the heart specialized cardiac muscle cells transmit electrical impulses from the atrioventricular node (AV node) to the Purkinje fibers – fascicles, also referred to as bundle branches. [citation needed] These start as a single fascicle of fibers at the AV node called the bundle of His that then splits into three bundle branches: the right ...
