Nabipur, A., Khanzadi, S. and Banihassan, M. 2002. Anatomy and histology of the atrio-ventricular bundle in the heart of goats (Capra hircus). J. Appl. Anim. Res., 22: 75-80. The detailed anatomy and histology of the atrio-ventricular bundle (AVB) was studied in 5 female goats. The trunk of the AVB was a direct continuation of the atrio-ventricular node (AVN) with no sharp line of demarcation between the node and the bundle. Histologically, the fibers of the AVB appeared to be organized into fascicles separated by the fine fibrous septa. The cells of the AVB were ovoid in shape with light cytoplasm and one or two central nucleus. The size of these cells were shorter and broader than working myocardial cells and stained paler than them. Myofibrils were located at the periphery of the cells and a large perinuclear clear zone was present. These cells showed faint cross striations and there were intercalated discs at intercellular connections.
