Hypodermic needle - Simple English Wikipedia, the free encyclopedia

A hypodermic needle is a hollow steel tube that is sharpened into a needle so it can be jabbed (inserted) into somebody's body. After it is in, medicine is pushed through the steel needle. The name "hypodermic" comes from two Greek words meaning "below skin".
