Are the vertebrae part of the integumentary system?
No, the vertebrae are the bones of the spinal column. These are part of the skeletal system. The Integumentary system is your skin.
There are three types of vertebrae. The seven (7) cervical vertebrae make up your neck and include the atlas and the axis. The next twelve (12) vertebrae are the thoracic and attach to ribs forming the thoracic cavity. The last five (5) vertebrae are the large lumbar vertebrae that form the lower arch of your back.
We can also count the five (5) vertebrae that have fused together to form the sacrum bone between the two pelvic bones.
