MUSCLE PHYSIOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -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.
