noun / verb
ridge
RIJ/rɪdʒ/
A long, narrow raised strip on a surface.
The narrow ridge has a continuous crest with slopes descending on both sides.

Etymology
Old English hrycg meant a person's or animal's back. Its use for a long, narrow crest draws on the projecting backbone of a four-legged animal—the same shape seen in a raised line of land.
In context
there’s a curved bony ridge known as the arcuate line. This marks the boundary between the ala and the body of the ilium
