Bone Function

What is very essential for bones to retain normal proportions and strength during long-bone growth as the body increases in size and weight?

• Osteoclasts

• Osteoblasts

• Bone Remolding

• Hematoma

The two strongest and most supportive tissues in the body are_______?

• Cartilage and Bone

• Blood vessels and Veins

• Osteoblasts and Osteoclasts

The forth stage in the healing of a bone fracture is ?

• Reduction

• Bone remodeling occurs

• Fibrocartilage callus forms

• Fossa

As more osteoblasts and osteoclasts migrate into the area and multiply, the fibrocartilage callus is gradually replaced by the _______ made of the sponge bone.

How does the skeletal system move our body?

• levitation
