Intrafascicularly terminating fibers

  • They make it virtually impossible to measure fiber length without dissecting out individual muscle fibers (which takes hours for each one).
  • The tapered endings mess up measurements of fiber cross sectional areas or diameters.
  • Their growth in length can mess up studies on the relative numbers of different histochemical types of fibers.

    I guess it's a lot easier to deny they exist. Make up your own mind!
