 Chapter 39: The vertebral column
The vertebral column usually consists of 33 vertebrae: 24 presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae).
The thoracic and sacral curvatures, termed primary, appear during the embryonic period proper, whereas the cervical and lumbar curvatures, termed secondary, appear later (although before birth) and are accentuated in infancy by support of the head and by the adoption of an upright posture.

The vertebral column is a flexuous and flexible column, formed of a series of bones called vertebræ.
The vertebræ are thirty-three in number, and are grouped under the names cervical, thoracic, lumbar, sacral, and coccygeal, according to the regions they occupy; there are seven in the cervical region, twelve in the thoracic, five in the lumbar, five in the sacral, and four in the coccygeal.
With the exception of the first and second cervical, the true or movable vertebræ present certain common characteristics which are best studied by examining one from the middle of the thoracic region.

 Release No. 0020.06
Under U.S. regulations, the backbone, or the vertebral column, which was exported to Japan would not be a "specified risk material" because it was from beef under 20 months old.
However, as you know our agreement with Japan is to export beef with no vertebral column, and very clearly what we have learned about this shipment is that it failed to meet the terms of that agreement.
And the person who certified it did certify it, and for whatever reason just did not connect to the fact that the vertebral column needed to be removed before it arrived in Japan.
