How Does A Bone Break Heal - Bone Fracture Healing Process

Which cell type will destroy any dead bits of bone in the injured area?

• Chondroblast

• Osteoblast

• Osteoclast

• Fibroblast

What trend do you notice about these cell types that end in 'blast'?

• cells that build

• cells that destroy

The first step to REPLACING the broken bone is through the chondroblasts laying down:

• bone

• ligaments

• cartilage

• tendons

You can see the bony callus is a little larger than the bone.  Which cells would be helpful in remodeling the callus to match the shape of the long bone?

• Osteoblasts

• Osteoclasts

• Osteocytes

Which bones tend to heal faster?

• younger

• older
