Tail bone vestigial fused vertebrae?
The tailbone, also known as the coccyx, is formed by the fusion of several small vertebrae that are no longer functional in humans. These fused vertebrae are considered vestigial remnants of our evolutionary history when our ancestors had tails. Today, the coccyx serves as an attachment point for muscles and has limited functional significance.
How many vertebrae does an adult have?

What does the coccyx lack?
Since the spinal cord ends just before the coccyx begins, coccygeal vertebrae also lack a central foramen (hole).

Transverse foramen?
Foramen lateral to the pedicle area. ONly cervical vertebrae have transverse foramen. Therefore, only cervical vertebrae have three holes. All other vertebrae have just one hole. The vertebral artery passes through these foramen.
