Diagram of distribution of substances in a striated muscle fibre tween anisotropic bands, which presumably contain the greater part of the myosin of the cells, and the isotropic bands. The former bands rotate the plane of polarisation of plane polarised light, whereas the isotropic bands do not. Cytochemical studies on muscle cells are at present rather scanty. It is known that adenosine triphosphate is concentrated in the isotropic bands, and that these bands also contain a relatively labile alkaline phospha- tase. Whereas acetone resistant acid phosphatase and desoxyribose nucleic acid are both mainly present in the.
