Which term describes a prominent ridge or crest on bone?

• A. Crest
• B. Line
• C. Epicondyle
• D. Tuberosity

Answer: (A)

A prominent ridge or crest on a bone is called a crest. This term refers to a narrow, raised edge that stands out from the bone surface and often serves as a site for muscle or ligament attachment, like the iliac crest in the pelvis. A line is a much less noticeable, thinner ridge, not as prominent as a crest. An epicondyle is a projection near a joint above a condyle, typically for ligament or tendon attachment but not described as a ridge. A tuberosity is a larger, rough bump for muscle attachment, which is coarser and more spread out than a crest. So, the best term for a conspicuous ridge on bone is crest.
