What is the term for a narrow ridge of bone that is less prominent than a crest, such as the linea aspera?

Explanation:
In bone markings, a line names a slender ridge that isn’t as prominent as a crest. The linea aspera on the femur is exactly that—a long, narrow ridge along the bone’s shaft where muscles attach. A crest is a much more pronounced, raised border, like the iliac crest. A process is any projection, and a tubercle is a small rounded bump. So the term for a narrow ridge such as the linea aspera is line.
