True or False: Alpha motor neurons innervate skeletal muscle fibers and thus impact their state of contraction. AP firing along gamma motor neurons impacts the state of contraction of ends of the muscle spindle (intrafusal), so that the spindle quickly reestablishes communication even when the extrafusal muscles shorten. Coactivation of both sets of fibers causes the tension in the skeletal muscle fibers to be maintained as the muscle shortens; thus sensitivity to stretch is maintained. True False
