Sacrum

We've learned about most of the bones in your spine,
the cervical vertebrae, thoracic vertebrae, and lumbar vertebrae.

There are two more parts on your spine at the very bottom.
The first one is called the sacrum, a somewhat large triangle shaped bone right in the middle of your hips.

sacrum by itself:

(from: wikipedia - sacrum)

We'll learn about the other part next Tuesday!
