Muscle is a term used to describe a type of tissue in the human body that is responsible for movement. It is made up of bundles of long fibers that contract and relax to produce force. In addition to movement, muscles also play a key role in supporting the body's structure, maintaining posture, and regulating body temperature. Muscles are classified into three main types: skeletal, smooth, and cardiac. Skeletal muscles are attached to bones and enable voluntary movements such as walking or lifting objects. Smooth muscles are found in the walls of organs and blood vessels, and are responsible for involuntary movements like digesting food or regulating blood flow. Cardiac muscle is specific to the heart and ensures that it can contract effectively to pump blood throughout the body. In a more figurative sense, "muscle" can also be used to describe strength, power, or influence. For example, someone might use the phrase "flexing their muscles" to imply that they are showcasing their power or authority in a certain situation. Overall, the term "muscle" is multifaceted, encompassing both the biological tissue responsible for movement and the metaphorical concept of strength or power.
