This chapter also provides the orientation of centra, neural arches, and lateral components. The sacrum generally possesses 14 secondary centers. The chapter closes with an overall morphological summary of the vertebral column.doi:10.1016/B978-0-12-374635-1.00003-5C. Cunningham...
The vertebral column, or spinal column, is a series of thirty-three vertebrae stacked on each other that function to keep the body upright, connect the skull to the trunk, protect the spinal cord, and provide attachment sites for many musc...
In addition to having a visible and fast-developing notochord, the cosmopolitan tunicateCiona robustacan be easily transfected at the 1-cell stage with multiple plasmids to produce hundreds of synchronously developing embryos, and possesses a compact, fully annotated genome (~140 Mb)19, with most...
Together, this is compelling evidence that the notochord possesses a segmental pattern in these teleost species, which lays the foundation of centrum periodicity. The profound differences in how vertebral body segmentation is achieved across the vertebrates raises an important question – was the ...
It is located in close proximity to the vertebral column of the young cave bear; however, an immediate interaction could not be detected. Subject S9 walked slowly in direction to the deep part of the cave. Of the 76 footprints published so far in 2009 (Bégouën et al. 2009) for the...

According to the "three-column theory", the posterior column possesses approximately 24–30% of the pressure and approximately 21–54% of the rotational stress [16]. The integrity of the posterior column structure is very important to ensure the stability of the spine. Therefore, the complete ...

At least one genus in all three NWM families possesses a ligand variant. Pithecidae displays three OT ligands, all varying at position 8 in the OT molecule (Leu8-, Thr8-, and Ala8-OT). Primates in the family Atelidae also display three OT ligands (Leu8-, Pro8-, and Phe2-OT)....
