Key concepts
3 concepts
- 1
Your axial bones are found along your body’s vertical axis and provide skeletal support and organ protection, while your appendicular bones make up your limbs and help you move around.
- 2
Osteoblasts are bone-building cells that construct bones by secreting collagen and enzymes that absorb minerals, while osteoclasts break down bone tissue through a process called resorption.
- 3
Bone remodeling is supervised by osteocytes, which sense stress and strain and direct osteoclasts to break down damaged bone, followed by osteoblasts that rebuild the bone.
