Abstract
The myosatellite cells in the axial muscles of the sharkGaleus melastomus is found more frequently in the red muscle fibers than in the white fibers. The total length of the cell extensions is about 100 μm. In about 20% of all cases, the extensions were present in pairs, and it is concluded that the satellite cell processes bifurcate. Processes towards the intercellular space and towards the interior of the muscle fiber are also described. The cytoplasm of the satellite cells contain glycogen, Golgi elements, lysosome-like vesicles, granular endoplasmic reticulum and microtubules. It is concluded that the morphology of the satellite cells indicates a more active function than that of a dormant reserve myoblast.Keywords
