Which term describes a sharp, slender projection?

• A. Spine
• B. Crest
• C. Line
• D. Process

Answer: (A)

Understanding bone markings involves knowing how projections are described. A sharp, slender projection is called a spine. It conveys a pointed, blade-like extension, such as the spinous process on a vertebra or the spine of the scapula. In contrast, a crest is a broad, elevated ridge; a line is a thin raised line; and a process is a general term for any projection. So the term that best fits a sharp, slender projection is spine.
