The bulbus arteriosus of teleost fish is a thick-walled chamber that extends between the single ventricle and the ventral aorta. The functional importance of the bulbus resides in the fact that it maintains a steady blood flow into the gill system through heart contraction.

It has variously been called conus arteriosus, bulbus arteriosus, bulbus aortae, truncus arteriosus (Gegenbauer,1866; Parsons,1930), and even bulbus cordis (de la Cruz et al.,1999). The use of one term or another reflects the emphasis placed on a particular structure, on the fish class under study, or on embryological considerations. Some authors even use the same name to refer to heart

ment of the bulbus arteriosus in the phylogeneti-cally advanced bony fishes. The bulbus arteriosus of teleosts is an intrapericardial, elastic chamber that

  • The truncus arteriosus and bulbus cordis are divided by the aorticopulmonary septum. The truncus arteriosus gives rise to the ascending aorta and the pulmonary trunk. The caudal end of the bulbus cordis gives rise to the smooth parts (outflow tract) of the left and right ventricles (aortic vestibule & conus arteriosus respectively).[8] The cranial end of the bulbus cordis (also known as the
  • Its possible cause: during partitioning of the bulbus cordis and truncus arteriosus, the aorticopulmonary septum fails to follow a spiral course The straight septum results from failure of the conus arteriosus or pulmonary infundibulum to develop during incorporation of the bulbus into the ventricles
  • The bulbus cordis has multiple components, including the truncus arteriosus, conus arteriosus, and conus cordis. The truncus arteriosus is cranial to the aortic sac, to which it is connected, and gives off the pharyngeal arch arteries.
  • The conus arteriosus (in more primitive species), contracts to assist blood flow to the aorta. The bulbus anteriosus does not contract. The ventral aorta delivers blood to the gills where it is oxygenated and flows, through the dorsal aorta, into the rest of the body.
