What are the 3 components of bone remodelling
Replacement of old (or injured) bone tissue with new bone tissue,Balance of bone resorption and deposition,Happens throughout lifetime,
What are benifits of bone remodelling
Exercise/heavy loads = stronger bone,Resistant to fracture
How does bone remodelling occour
Osteoclast – attaches to bone surface, acids dissolve bone minerals, tunnel is formed, calcium enters cell via endocytosis and exit into bloodstream via exocytosis, then they leave the bone.Osteoblasts – move in to rebuild the bone in the area
