Our cervical spine is the neck region of our backbone. It consists of our first seven stacked bones called vertebrae, with the top of the cervical spine connected to the skull.
It is located in the upper and middle parts of the back. It is the longest spine region (twelve vertebrae) and is attached to the rib cage.
It is located in the lower back and has five vertebrae, the largest of our entire spine. The spine ends here and controls movements and sensations in the legs.
Sacrum & Coccyx
The very lowest part of the spine, located below the sacrum, comprises a triangle of bones called the coccyx (vestigial tail). The sacrum is a triangular-shaped bone of five fused segments.
