Question

which of the following refers to width-wise growth to increase the diameter of long bones?

appositional growth
primary ossification center
secondary ossification center
interstitial growth

Explanation:

Define bone growth mechanisms

• Appositional growth: Growth in diameter/thickness by adding bone tissue at the surface.
• Interstitial growth: Growth in length occurring at the epiphyseal plate.

Evaluate the options

• Apposition Growth: Increases diameter (width-wise growth).
• Primary/Secondary Ossification Center: Sites of bone formation during development.
• Interstitial Growth: Increases length.

Identify the correct choice

• The term for width-wise growth to increase the diameter of long bones is Appositional Growth.

Answer:

• Appositional Growth (Correct answer)
• Primary Ossification Center
• Secondary Ossification Center
• Interstitial Growth
