It is The upper and lower vertebral transverse processes were connected, which might affect their biomechanics. For example, baboons (Papio anubis) [36], which walk upright and are among the closest relatives to humans, have vertebrae with thinner pedicles, longer transverse processes, more prominent uncovertebral joints, and more horizontal spinous processes than humans. Pigs Calves and pigs are four-legged mammals with relatively easy-to-obtain cervical spines.

Make sure you can locate the following organs: Also in the abdominal cavity you will find the excretory system organs. PIG. The pig SCD and SCW were larger than those in humans at C2 (p<0.05) (Table 2). Anatomical morphometric analysis was performed on cervical vertebra specimens harvested from humans and two common large animals (i.e., calves and pigs). these other thoracic organs are basically the same in pigs and humans. This current study is the first to compare cervical vertebrae anatomy between pigs, calves and humans. Because having a longer small intestine helps you extract nutrients from your diet, this finding supports the canalization hypothesis, which posits that women are better able to survive during periods of stress, says Hale.
