7. Dieseses

7.1. Examples

7.1.1. Osteoporosis Bones become braise and fragile due to loss of tissue

7.1.2. Scoliosis When the backbone curves to the side

8. Fractures

8.1. Examples

9. Bone Cells

9.1. Types of Bone cells

9.1.1. Osteocytes They maintain the matrix Rebuild the matrix after destroying it with chemicals Play a role in bone repair and remodling Cannot divide

9.1.2. OsteoBlasts Produce new bone matrix= Ossification Make and release the proteins and other compounds of the matrix Surrounded by Matrix

9.1.3. Osteoclasts 50 or more nuclei Remove and recycle bone matrix Secrete acids and proteolytic enzymes to dissolve matrix and release stored minerals= Osteolysis
