Disk lesions are more common in the 30- to 45-year age span because:
A) The annulus begins degenerating,loses tensile strength,and begins to tear with excessive forces.
B) The nucleus pulposus changes in chemical composition during this time and is capable of imbibing greater than normal amounts of water,causing greater than normal pressure against pain-sensitive structures.
C) The facets are wearing out and the entire joint complex is placed under greater stress.
D) This is not the most common age span for disk lesions.

Question

The annulus fibrosus, the outer layer of the intervertebral disk, begins to degenerate and lose tensile strength as a person ages. This can cause it to tear with excessive forces, leading to disk lesions. This process typically begins in the 30- to 45-year age range.
