Which part of the needle is the sharpened edge?

• A. Bevel
• B. Hub
• C. Shaft
• D. Tip

Answer: (A)

The sharpened edge is the bevel. The bevel is the angled surface ground at the end of the needle, forming the cutting edge that allows it to pierce tissue smoothly. The tip is the very end point created by that bevel, but the actual sharp edge comes from the beveled surface. The hub is the plastic part that attaches to the syringe, and the shaft is the long body between hub and tip. Understanding this explains why the bevel’s angle and orientation matter for a painless, accurate injection.
