The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.
组2的心脏解剖困难,表现为纤维组织坚韧,游离肺动脉非常困难;徒手无法松解左、右纤维三角,肺动脉和主动脉根部的游离非常困难;心肌纤维坚硬、质脆,解剖时容易断离成碎块,无法沿纤维走行方向剥离。
