Skeletal muscle structure histology
WebbSmooth muscle. Compared to skeletal muscle, smooth muscle cells are small. They are spindle shaped and have no striations. Instead, they have bundles of thin and thick filaments. Looking closer at skeletal muscle. All skeletal muscle fibres are not the same. They differ in structure and function, for example, in the speed they can contract.

WebbThe skeletal muscle consists of striated muscle cells that are fused together into long muscle fibers. Transcriptome analysis shows that 65% (n= 13026) of all human proteins (n= 20090) are expressed in the skeletal muscle and 918 of these genes show an elevated expression in the skeletal muscle compared to other tissue types. 918 elevated genes. WebbThick filaments consist mostly of the proteins myosin and titin. Titin connects the thick filaments to the Z-line. There are about 300 molecules of myosin in each thick filament, and at the end of each molecule are …
