  • intrafusal fibers

  • The results of this study suggest that dystrophin is not an integral part of the subsynaptic sensory-membrane in equatorial regions of normal intrafusal fibers, and, that the neurotrophic effect of sensory innervation is not the principle cause of this unique arrangement of dystrophin in equatorial regions. (ubc.ca)
  • They increase the stretch-sensitivity of the Ia afferents by stiffening the bag1 intrafusal fibers. (wikipedia.org)
  • thereby
  • This raises the resting potential of the endings, thereby increasing the probability of action potential firing, thus increasing the stretch-sensitivity of the muscle spindle afferents. (wikipedia.org)
