Needle
A needle is a slender, pointed instrument typically made of metal, used to insert substances into, or extract them from, the body. Commonly associated with sewing, medical procedures, or injections, needles are designed to be sharp to minimize discomfort and facilitate easy penetration of skin or fabric. Medical needles, such as those used for injections or drawing blood, often attach to a syringe and are crucial for administering medications, vaccines, or collecting samples. Their precise, streamlined design helps ensure safety, accuracy, and comfort during various applications.
