column, widening toward the base, composed of a series of 

 separate bones called vertebras. 



Each vertebra has seven projections, four for joining 

 other vertebras (two upper and two lower), two side, and 

 one spinous.

How the Vertebras Fit Together. The smooth places 

 where the projections join are called facets. Observe on 

 each side of the body of the vertebra a facet where the 

 head of the rib joined it. There is also a facet on the side 

 process where the side of the rib joined it. 



The Cervical Vertebras. The seven rgrvical (neck) 

 vertebras have holes through their side projections for the 

 passage of blood tubes.
