A needle consists of three parts: the hub, the shaft, and the bevel. The hub is the part of the needle that attaches to the syringe. The shaft is the long, thin part of the needle that penetrates the skin. The bevel is the slanted tip of the needle that allows it to pierce the skin more easily. Needles also come in different gauges, which refers to the thickness of the shaft. The higher the gauge, the thinner the needle.

A syringe consists of three parts: the barrel, the plunger, and the needle. The barrel is the part of the syringe that holds the medication. The plunger is the part of the syringe that is used to push the medication out of the barrel and into the patient’s body. The needle is the part of the syringe that attaches to the hub of the needle. Syringes also come in different sizes, ranging from 1 mL to 60 mL.
