I. FUNCTION AND TYPES OF MUSCLE. Locomotion: One of the most obvious functions of muscle tissue is locomotion. When muscles contract, the fibers pull or relax bones to which they are attached, thus causing locomotion. Muscle contraction is also the primary means of moving lymph in the lymphatic vessel.
The organ systems carry out the functions of the body such as digestion, communication, circulation, respiration, excretion, and movement. Tissues may be categorized into four major types: (1) epithelial, (2) connective tissue, (3) muscle, and (4) nervous tissue.The cells of tissues are held together by one or more of a variety of cell junctions.uscle tissues.
