Yan Lin, Coil bound. Because the methods are relatively novel, various improvements are still needed, and it is thus helpful to conduct experimental surgeries on pig livers. 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. government site. Pigs are also attractive animal models due to their similarities with humans in anatomy and metabolism [34]. 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. This current study is the first to compare cervical vertebrae anatomy between pigs, calves and humans.

Thought pigs and humans are similar there are still some differences. Due to the potential for infection, the limited supply of human cadavers, and the ethical concerns surrounding the use of human specimens, vertebrae from animal models, such as pigs [19], calves [1019], dogs [2027], sheep [2831] and deer [3234],have been widely used in spine research to replace human vertebrae.
