These repeated segments ensure that the rod-like spinal column can hunch, arch, and twist. ... “There is huge variability in the number of vertebrae among different animals, ...

This configuration marks a transition toward the type of spinal column that allows humans to be the efficient, athletic walkers and runners of today. “We are documenting, for the first time in the ...

The vertebrae that make up the cervical spine are the smallest seven within the spinal column. These bones give the neck structure, support the skull, and protect the spinal cord, among other ...
