LESSON 5 SHORT QUIZ

Question 1

Which process involves interstitial growth of cartilage on the epiphyseal side and endochondral ossification on the diaphyseal side of the epiphyseal plate?

• Bone deposition
• Appositional growth
• Bone resorption
• Bone remodeling

Answer 1

Appositional growth

Question 2

What are the four zones found in the epiphyseal plate during bone growth?

• Resting cartilage, hypertrophic cartilage, osteoblasts, osteoclasts
• Resting cartilage, proliferating cartilage, hypertrophic cartilage, calcified cartilage
• Resting cartilage, calcified cartilage, hypertrophic cartilage, osteocytes
• Resting cartilage, proliferating cartilage, osteoblasts, osteoclasts

Answer 2

Resting cartilage, proliferating cartilage, hypertrophic cartilage, calcified cartilage

Question 3

How does bone lengthening occur during growth?

• By adding more layers of cartilage to the epiphyseal plate
• By the replacement of cartilage with bone on the epiphyseal side
• By the activation of osteoclasts in the epiphyses
• By the replacement of cartilage with bone on the diaphyseal side

Answer 3

By the replacement of cartilage with bone on the epiphyseal side

Question 4

When does the epiphyseal plate typically close, marking the end of longitudinal bone growth?
- During infancy
- During childhood
- When adulthood is reached
- During adolescence

Answer 4

During adolescence

Question 5

How does bone grow in thickness (diameter)?

• By the formation of new cartilage
• By appositional growth, involving periosteal cells and osteoblasts
• By the breakdown of collagen fibers
• By the division of osteoclasts

Answer 5

By appositional growth, involving periosteal cells and osteoblasts

Question 6

Which process involves the removal of minerals and collagen fibers from bone by osteoclasts?

• Endochondral ossification
• Bone deposition
• Bone remodeling
• Bone resorption

Answer 6

Bone resorption

Question 7

Approximately what percentage of the total bone mass in the body is undergoing remodeling at any given time?

• 10%
• 1%
• 5%
• 25%

Answer 7

5%

Question 8

What triggers bone remodeling in the body?

• Vitamin D deficiency
• Sedentary lifestyle
• Decreased protein intake
• Increased intake of calcium

Answer 8

Increased intake of calcium

Question 9

What is one of the benefits of bone remodeling?

• Increased bone strength in response to heavy loads
• Decreased bone strength
• Reduced bone density
• Increased risk of fractures

Answer 9

Increased bone strength in response to heavy loads
