9. Bone Cells: Remodeling Over Years
Your skeleton is far from static. Specialized bone cells—osteoclasts (which break down bone) and osteoblasts (which build new bone)—are constantly at work reshaping your bones.
This process, known as bone remodeling, ensures that most of your skeleton is replaced roughly every 10 years. It allows bones to adapt to stress, repair damage, and regulate minerals in the body. For a detailed overview of bone cell turnover, refer to NCBI Bookshelf.
