1. Cervical Vertebrate: These are the group of seven vertebrae of the neck, start immediately below the skull. Two cervical bones C1 and C2 are unique in function. They are responsible for the movement of the head. They have transverse foramina which gives passage to vertebral artery and vein.

4. Sacrum Vertebrae: There are 5 sacral vertebral fused bones. It connects to the hip bones and play role in forming a strong pelvis.

5. coccyx Vertebrae: These are a group of 4 fused bone. There is no vertebral canal due to a lack of vertebral arches. They provide an attachment site for muscles ligament and tendons. They also play a role in stabilization and support while sitting.
