👉 A constrictor is a type of muscle in the body that contracts when needed, such as to narrow or close an opening. It is typically found in large muscles and can be used for various purposes, such as restraining oneself from hurting themselves, controlling movement, or closing up a wound. Examples include the biceps muscle in the arm, which contracts tightly to keep a person's arms locked tight, and the quadriceps muscle in the leg, which contracts to hold an object in place while bending
