The cranial end of the bulbus cordis (also known as the conus cordis) gives rise to the aorta and pulmonary trunk with the truncus arteriosus. This makes its appearance in three portions. Two distal ridge-like thickenings project into the lumen of the tube: the truncal and bulbar ridges. [3] See more The truncus arteriosus is a structure that is present during embryonic development. It is an arterial trunk that originates from both ventricles of the heart that later divides into the aorta and the pulmonary trunk See more The truncus arteriosus and bulbus cordis are divided by the aorticopulmonary septum.
