Syringe Needle (Standard 22-gauge)
A hollow tube thinner than a strand of spaghetti/Medicine & Biology
A standard 22-gauge hypodermic needle has an outer diameter of 0.718 mm and an inner diameter of 0.413 mm. The needle's tip is ground at a precise angle to minimize tissue damage during insertion. Modern needles are coated with a thin layer of silicone to reduce friction. Despite being feared by many, the needle's design is an elegant piece of precision engineering.
