Muscle is the fibrous tissue in an animal or human body that contracts and expands in order to create movement, either internal or external. The word muscle is also used to describe someone or something that is powerful or influential or something that is accomplished through force. Informally, muscle also indicates a person who is physically strong or whose job it is to enforce rules. Muscle is derived from the Latin word musculus.
