It is formed from individual bones called vertebrae (singular: vertebra), which houses the spinal canal, a cavity that encloses and protects the spinal cord.There about 50,000 species of animals that have a vertebral column.ertebrae are defined by the regions of the vertebral column that they occur in. Cervical vertebrae are those in the neck area. With the exception of the two sloth genera (Choloepus and Bradypus) and the manatee genus, (Trichechus), all mammals have seven cervical vertebrae.
