Muscle tissue Muscle tissue has a ability to relax and contrast and so bring about movement and mechanical work in various parts of the body. There are other movements in the body too which are necessary for the survival of the organism such as the heart beat and the movements of the alimentary canal. Muscles can be divided into three main groups according to their structure * Smooth muscle tissue. * Skeletal muscle tissue. * Cardiac (heart) muscle tissue.
