One heart displayed a transmural course of the left coronary artery arising from the nonfacing sinus. by measurement, the subpulmonary length was, on average, roughly 50% greater than the subaortic length, and, when the selected hearts were sectioned, much of the subpulmonary infundibulum was found to be composed of free-standing musculature rather than true outlet septum. the proportion of.

The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate animal, including humans. the primary divisions of the skeleton system are the head, thorax, and vertebral column. infiltrative processes that extend into the intervalvular fibrosa, such as infection or calcification, often mandate a complex reconstructive procedure known as the commando operation.
