The bone cells responsible for removing excess bone tissue after the fracture repair process are called?

• fibroblasts

• chondrocytes

• osteoblasts

• octeoclasts

Osteoblasts are _________________, where as osteocytes are _________________.

• bone-forming cells; bone chewing cells

• mature bone cells; bone-forming cells

• bone-destroying cells; bone-forming cells

At what age are all bones normally ossified?

• birth

• 5 years

• 10 years

• puberty

A compound fracture:

• is caused by an injury

• is caused by infection

• results when the broken bone is exposed to the outside environment

• results when the bone is broken more than once
