MICROANATOMY

Detailed explanation-1: -Skeletal muscle fibers are cylindrical, multinucleated, striated, and under voluntary control. Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations.

Detailed explanation-2: -Muscle Cell / Fibroblast Nuclei-muscle cell nuclei are mostly euchromatic and have a flattened, oval shape. Fibroblast nuclei are located between muscle cells and are more elongated and darker.

Detailed explanation-3: -With an average diameter of 10 m, nuclei are normally found at the periphery of the myofiber, just below the plasma membrane. Nuclear positioning at the periphery of myofibers is a hallmark of skeletal muscle although the function of this structural characteristic remains elusive.

Detailed explanation-4: -Skeletal muscle looks striped or “striated” – the fibres contain alternating light and dark bands (striations) like horizontal stripes on a rugby shirt. In skeletal muscle, the fibres are packed into regular parallel bundles.
