a - closing of the epiphyseal plate
b - appositional growth
c - epiphyseal plate closure
d - concentric growth

Explanation:

Analyze the question prompt

The question asks for the biological term describing the process of bones increasing in width or thickness.

Evaluate the options

Using the Skeletal Development knowledge point

• A - closing of the epiphyseal plate: This refers to the cessation of longitudinal bone growth.
• B - appositional growth: This is the process where osteoblasts in the periosteum secrete bone matrix on the external surface, increasing bone thickness/width.
• C - epiphyseal plate closure: This is synonymous with option A, marking the end of growth in length.
• D - concentric growth: This is not a standard anatomical term for bone widening.

Select the correct option

The term for bone growth in width is appositional growth.

Answer:

• (A) closing of the epiphyseal plate
• (B) appositional growth (Correct answer)
• (C) epiphyseal plate closure
• (D) concentric growth
