What happens to bones as a person ages, according to musculoskeletal system changes?

As a person ages, one significant change in the musculoskeletal system is that bones become more brittle. This occurs due to a variety of factors including decreased bone density and changes in the composition of bone tissue. Over time, the balance between bone resorption (the process where bone is broken down) and bone formation tends to tip towards resorption, leading to a weakening of the bone structure. As a result, older adults are at a higher risk for fractures and injuries, particularly from falls.

The deterioration in bone density not only makes bones more susceptible to breaks but also contributes to conditions like osteoporosis. This understanding is crucial for caregivers and healthcare professionals when assessing and providing care for elderly individuals, emphasizing the need for fall prevention strategies and adequate nutrition to support bone health.

The other options do not accurately reflect the changes that occur in bones with aging. Bones do not become more flexible; rather, they lose flexibility as tissue becomes stiffer. Bones do not grow larger; instead, they tend to shrink in size and strength. Finally, while there is some loss of mass, the more pertinent issue is the increased brittleness due to structural weakening.
