Disk lesions are more common in the 30 year 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

Quizplus · Accepted Answer

The annulus fibrosus, the outer layer of the intervertebral disc, begins to degenerate and lose its tensile strength during the 30 to 45 year age span. This results in tears or fissures which can lead to disk herniation or bulging, making disk lesions more common during this age group.
