Abstract

This chapter discusses various aspects of muscle, a tissue composed predominantly of cells that are specialized to shorten in length by contraction. The force generated by contraction of a muscle fiber is transmitted to other structures through connective tissue. Each muscle fiber is closely invested by connective tissue that is continuous with that around other muscle fibers. Skeletal muscle, cardiac muscle, and smooth muscle, are some topics discussed in detail. In some animals complete muscles may consist exclusively of red or white fibers, but in most mammals, including man, muscles contain an admixture of both types. The fibers of cardiac muscle do not run in strict parallel formation, but branch and anastomose with other fibers to form a network. Cardiac muscle is involuntary and is innervated by autonomic fibers and nerve endings terminate near the cardiac myocytes, but motor end plates are not seen. Smooth muscle and cardiac muscle have very little capacity for regeneration. Any defects produced by injury or disease are usually repaired by formation of fibrous tissue.
