in the number of cells or fibers. A single muscle cell is usually called a fiber. HOW DO MUSCLE FIBERS ADAPT TO DIFFERENT TYPES OF EXERCISE?However no comparative study exists comparing the histologicaladaptations in response to 1 Edman KA P.: "Contractile Performance of Skeletal Muscle Fibers....
A characteristic of intact mature fibers is that the cell nuclei are located in the fiber periphery, that is, under the electrically excitable plasma membrane or sarcolemma. Conversely, cell nuclei are lined up centrally in myotubes, and immature and regenerating fibers. Muscle Fiber. Fig. 1 ...
