How does aging generally affect the spine?

As individuals age, the spine undergoes various physiological changes, which typically lead to degeneration of its components, including discs and joints. This degeneration is characterized by a decline in the hydration and elasticity of intervertebral discs, making them less effective as shock absorbers. Additionally, the cartilage in the facet joints may wear down, resulting in increased friction and potential arthritis, which can further contribute to discomfort and mobility issues.

This age-related degeneration can lead to a series of conditions, such as spinal stenosis, herniated discs, and spondylosis. These changes are natural and often result in a reduction in overall spinal flexibility and an increase in stiffness, rather than an improvement in mobility or flexibility. Hence, the correct identification of option B reflects the typical spinal changes seen with aging, emphasizing the importance of understanding these natural processes in the context of spine health.
