The pig cervical spine is highly similar to the human cervical spine, except for two large transverse processes in the anterior regions ofC4C6.

This finding supports the female canalization hypothesis, specifically, increased female investment in the digestion and absorption of lipids. In addition to shedding light on the unexpected variability in human anatomy, this project also led to rediscovering the importance of teaching anatomical variation to medical students.

A prominent left azygous vein (comparable to the much reduced left superior caval or oblique vein in man) entered on the left side of the pig heart and drained via the coronary sinus. Anatomical reference terms may be confusing because they are different for pigs that walk on four legs vs. upright, bipedal humans.

Humans do not have a bicarotid trunk; instead, the left common carotid artery branches from directly from the aorta, while only the right common carotid artery originates from the brachiocephalic artery. Except for the length, the means of the other morphometric measurements of the pig kidney are smaller than those of humans. Its increasingly clear that the medical field is moving toward individualized medicine to improve patient outcomes and overall health and well-being. Learning Objectives. The fetal pig develops primary teeth (which are later replaced with permanent teeth). Calf C1-2 had a different morphology than human C1-2. How many chambers does the pig heart have? However, a systematic quantitative comparison of anatomical data corresponding to pig, calf, and human cervical vertebrae has not been reported. 2 What do pigs and humans have in common? There are some differences in the location of chest muscles that attach to the shoulder girdle.
