The largest difference between pig and human middle and lower cervical vertebrae was the presence of two anterior transverse processes in pigs; these were located in the coronal area. The pig cervical spine is highly similar to the human cervical spine, except for two large transverse processes in the anterior regions ofC4C6. How genetically similar are pigs and humans? We conclude that, although the shapes of the human and pig livers are quite different, the pig liver is divided into the same number of segments as the human liver, which also shows a common structure of the vascular system.
