pelvis
What does the sacrum bone do?
the sacrum is part of the vertebral column. it is made up of five bones that fuse together over time
What are the bones below the sacrum called?
The Coccyx bone, which is a very small triangular bone forming the end part of the spine. It is actually 4 separate bones which are fused into one.
What bone articulates with the sacrum?
The spine (specifically L5, the 5th lumbar vertebra). The pelvis also attaches to the sacrum but I think that joint is fused.
What is the reason of the coccyx bone?
The spine has to end somewhere, and that last vertebra is called the coccyx. If it didn't end there, we would have tails.
