Muscle tissue is the primary tissue type responsible for movement in the body. It is composed of specialized cells that can contract and generate force. There are three types of muscle tissue: skeletal muscle, which is under voluntary control and responsible for moving bones; cardiac muscle, found only in the heart and responsible for pumping blood; and smooth muscle, which is involuntary and found in the walls of hollow organs, aiding in processes like digestion and blood vessel regulation.

The unique ability of muscle tissue to contract differentiates it from the other tissue types. While nervous tissue plays a crucial role in signaling and processing information, and connective tissue supports and binds other tissues, they do not facilitate movement on their own. Epithelial tissue serves primarily as a protective layer and is involved in absorption and secretion. Therefore, muscle tissue's inherent contractile ability makes it the primary tissue responsible for generating movement in the body.
