Mccune-Albright Syndrome Anatomy
To better understand fibrous dysplasia, it helps to understand the anatomy of the skeleton and bone
The bony skeleton is a living structure that supports the entire body. Bone made up of an outer shell of cortical, or very dense, bone that surrounds a honeycomb-like structure of softer (cancellous) 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: a total of 80 bones including the skull, spine, and chest
- Appendicular skeleton: a total of 126 bones including the pelvic girdle, limbs, feet and hands
