Ultrastructural Organization of Obliquely Striated Muscle Fibers in Ascaris Lumbricoides
The somatic musculature of the nematode, Ascaris, is currently thought to consist of smooth muscle fibers, which contain intracellular supporting fibrils arranged in a regular pattern. Electron microscopic examination shows that the muscle fibers are, in fact, comparable to the striated muscles of vertebrates in that they contain interdigitating arrays of thick and thin myofilaments which form ...

متن کاملNon-centrosomal Microtubule Organization in Differentiated Cells
The centrosome consists of a pair of centrioles surrounded by pericentriolar material. During the formation of the mitotic spindle, multi-protein complexes in the pericentriolar material are involved in the nucleation and anchorage of microtubules. In postmitotic cells of many tissues, proteins of the pericentriolar material lose their association with the centrosome and redistribute to various...
متن کاملTumors of striated muscle.
Three benign forms of muscle tumors and three variants of rhabdomyosarcoma are discussed from the point of view of their histology and behabior. Recent combined modality therapy has significantly improved the prognosis in at least the embryonal form of rhabdomyosarcoma.
متن کاملFilament Lengths in Striated Muscle
Filament lengths in resting and excited frog muscles have been measured in the electron microscope, and investigations made of the changes in length that are found under different conditions, to distinguish between those changes which arise during preparation and the actual differences in the living muscles. It is concluded that all the measured differences in filament length are caused by the ...
