Where is the Epiphyseal Ring located in adult humans?

The Epiphyseal Ring, also known as the epiphyseal line, is a remnant of the growth plate found in long bones after growth has ceased. In adult humans, this structure can be observed in the femur, among other long bones, as it reflects where the epiphyseal plate was located during the growth period.

In vertebrae, while they have a complex structure that includes epiphyseal growth plates during development, the term "Epiphyseal Ring" is more specifically related to long bones. The same goes for the skull and pelvis; they do not commonly reference the Epiphyseal Ring in the context of their anatomy post-maturity. Thus, the most appropriate choice regarding the location of the Epiphyseal Ring in adult humans is in the femur as it is a primary example of long bones where these features are typically discussed.
