A crest is a narrow, prominent ridge on a bone, often serving as a strong attachment site for muscles and ligaments. It stands out more than other ridges, which is why it’s the go-to term for that feature. For example, the iliac crest along the pelvis is a classic, easily felt ridge. By comparison, a line is a thinner, less conspicuous ridge; a process is any projection or outgrowth from bone; and a tubercle is a small, rounded bump. So the term that best fits a narrow yet prominent ridge is crest.
