To better understand chondroblastoma, it helps to understand bone and skeletal anatomy.
The skeleton is a living structure that supports the entire body. Bone is made up of an outer shell of very dense bone that surrounds a honeycomb-like structure of softer bone. Bone mainly consists of protein and calcium. Without calcium, bone will become weak.
The human skeleton can be divided into two sections:
- Axial skeleton:
- Appendicular skeleton:
- A total of 126 bones including the pelvic girdle, limbs, feet and hands
