muscle fiber is comparable to thecytoplasm of other cells, but it houses unusually large amounts of "glycosomes" (granules of storedglycogen ) and significant amounts ofmyoglobin , anoxygen binding protein. The calcium concentration in sarcoplasma is also a special element of the muscular fiber by means of which the contractions takes place and regulates.Other than the fact that it contains mostly
myofibrils its contents are otherwise comparable to those of the cytoplasm of other cells. It has aGolgi apparatus , near the nucleus,mitocondria just on the inside of the cytoplasmic membrane orsarcolemma , as well as asmooth endoplasmic reticulum organized in an extensive network.External links
