Abstract
Aim – an electron microscopic study of the muscle tissue of levator ani muscle in human.
Material and methods. The paper describes the muscle tissue of levator ani muscle. The data was obtained by light-optical and electron microscopic examination of muscle tissue.
Results. The study of the ultrastructural organization of the muscle tissue of levator ani muscle in human shows that it corresponds to the structure of skeletal muscle tissue – it consists of muscle fibers that are cellular-symplastic structures. The main volume of the myosimplast is occupied by myofibrils located along its longitudinal axis, having a distinct sarcomeric organization – sarcomeres are separated by Z-lines, a dark disс is located on both sides of the centrally located M-line, light disсs are located on both sides of the Z-lines.
Conclusion. Levator ani muscle in human belongs to the striated skeletal muscle tissue of the locomotor type.
