33 individual bones hehe I'm only 12 and i know that lol ily yall
Back Bone: your spine...made of spinal vertebrae
Bone
The Spine is made up of many smaller bones, which is what allows flexing and movement of the spine. Please see the related links for a detailed picture of the bones that make up the spine.
about 8 bone
yes if it has a spine, it doesn't matter if it is made of cartilage
The connection is made with ligaments and connective tissues. Below the lumbar spine is the sacrum. The sacrum is actually a group of specialized fused vertebrae that connects the spine to the pelvis.

The spine is made up of vertebrae.
I think that it is 7
I'm assuming you mean the spine - The highest 7 vertebrae make up the cervical spine (or C spine) = the neck The next 12 vertebrae (where your ribs attach) make up the thoracic spine (or T spine) - this can also be referred to as the dorsal spine The next 5 vertebrae down make up the lumbar spine (or L spine) = the lower back And the sacrum is the very bottom of the spine made of 5 fused vertebrae.
The cervical region of the spine contains 7 vertebrae. The best motion in this are is rotation. C1 (the atlas) and C2 (the axis) are specialized bones of rotation.
The freely movable joints in the spine are called facet joints. These joints are located on the back of each vertebra and allow for movement and flexibility in the spine. The facet joints work together with the intervertebral discs to facilitate various spinal movements such as bending forward and twisting.
