Final answer:
Indicators of an older adult when observing the pubic symphysis include increased size and thickness, osteophytes, and wear on the surface.
Step-by-step explanation:
Indicators of older adults when looking at the pubic symphysis include:
- Increased size and thickness of the pubic symphysis
- Development of osteophytes (bony outgrowths) on the pubic symphysis
- Wearing down of the pubic symphysis surface
These changes occur due to the natural aging process and can be observed through radiographic imaging or examination of skeletal remains.
