As legs age, several changes occur affecting their structure and function. The legs might appear longer relative to the trunk due to changes in bone mineral density and joint flexibility.
Here's a breakdown of the aging process in legs:
- Bone Changes:
- The long bones in the legs become more brittle due to mineral loss. The reference states: "The long bones of the arms and legs are more brittle because of mineral loss, but they do not change length."
- Although the bones don't change length, the overall body proportion may shift.
- Joint Changes:
- Joints become stiffer and less flexible, limiting range of motion.
- Fluid within the joints may decrease, contributing to stiffness and discomfort. The reference states: "The joints become stiffer and less flexible. Fluid in the joints may decrease."
- Appearance:
- The legs may look longer compared to the trunk due to a combination of bone brittleness and a shortened trunk. The reference states: "This makes the arms and legs look longer when compared with the shortened trunk."
| Change | Description | Consequence |
|---|---|---|
| Bone Brittleness | Mineral loss in long bones of the legs. | Increased risk of fractures. |
| Joint Stiffness | Reduced flexibility and decreased fluid in the joints. | Limited range of motion and discomfort. |
| Proportion Shift | Legs appear longer relative to a possibly shortened trunk. | Altered body appearance. |
