Bone Formation and 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

Bones must widen as they lengthen. What is the processes called in which increase in diameter?

• Appositional growth

• Impacted fracture

• Greenstick

• Open reductions

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

• Bony Callus

• Hematoma

• External callus

• Facets

Bones are very strong, but can be susceptible to__________?

• Calcification

• Brittleness

• Fractures

• Twisting

What is the first stage in the healing of a bone fracture?

• Bony callus forms

• Bone remolding occurs

• Bony callus forms

• Hematoma forms

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

• Cartilage and Bone

• Blood vessels and Veins

• Osteoblasts and Osteoclasts

A fracture is treated by _________, which is the realignment of the broken bone ends.......

• Rickets

• Bone remodeling

• Bony callus

• Reduction

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

• Reduction

• Bone remodeling occurs

• Fibrocartilage callus forms

• Fossa

Bones remodeled continually in response to changes in two factors:

• (1)Bones start to weaken(2) the growth of new capillaries

• (1)Calcium levels in the blood and (2) the pull of gravity and muscles on the skeleton.
