Bone Formation, Growth, & Remodeling

Mostly hyaline cartilage

Replaced by bone

Growth & Remodeling New cartilage is

continuously formed

Older cartilage becomes ossified

Cartilage is broken down by osteoclasts

Buit by osteoblasts

Growth & Remodeling Osteocytes can sense

areas of stress

Enhances the process
