And so the muscle cell that I'm writing out over here-- it has a special name, as well. So we can call it a muscle cell, but we can also call it a myo-- myo meaning muscle-- fiber. So this is shaped like a fiber, because it is longer than it is wide.

WebbSkeletal or Striated Muscle Skeletal muscle tissue is distinctive due to its long, tube-shaped multinucleated fibers (cells) with visible cross-striations. The striations are the result of highly ordered actin and myosin filaments within sarcomeres , the basic contractile units of muscle fibers (see images below).

Webb8 apr. 2024 · Cardiac-muscle cells have striations, or stripes, because they are composed of two different types of fibers in bands, and they are closely interconnected with structures called intercalated discs. This interconnection allows the cardiac-muscle cells to contract easily, in unison; that ability keeps the heartbeat synchronized.

WebbSmooth Muscle Cells Smooth muscle fibers are long, spindle-shaped (fusiform) cells. Note the single and centrally placed nucleus in each smooth muscle cell. The absence of striation is also characteristic of the smooth muscle cells. How does the number and location of the nuclei in smooth muscle compare to that in striated muscle?

Satellite cells are situated between the external lamina and sarcolemma. The satellite cells are precursors to skeletal muscle cells and are responsible for the ability of muscle tissue to regenerate.
