In almost every case, fetal pigs have the same muscles as humans, with some small variations in the size and location of some muscles related to the fact that pigs are quadrupedal and humans are bipedal. Necessary cookies are absolutely essential for the website to function properly.

Thymus the thymus is found in the same areas in pigs as in humans. This current study is the first to compare cervical vertebrae anatomy between pigs, calves and humans. Several differences existed between humans and calves: 1. Many investigations on surgical methods and medical treatment are currently done on pigs. This field is for validation purposes and should be left unchanged. The biomechanical properties of nerve vascular anatomy and various segment functions in pig and calf cervical vertebrae must be considered when selecting an animal model for research on the spine.

Calves and pigs are four-legged mammals with relatively easy-to-obtain cervical spines. When considering these two animal models as human substitutes for in vitro and in vivo experiments, the biomechanical properties of their nerve vascular anatomies and functions across various spinal segments must be taken into account.
