[Trophic significance of sensory innervation of the skeletal muscles--an experimental study on the m. sternomastoideus of the rat].
In this study the morphological changes of the sternomastoid muscle of the rat caused respectively by division of sensory afferents, the motor efferents and by total denervation of the muscle are investigated one, two, three and four months after surgery using sections from the middle part of the muscle stained by Sudan-Black-B, Succinodehydrogenase- and ATP-ase-reagent. Small quantitative changes, as shown in curves of distribution of the sizes of muscle fibers, and a remarkable increase in the density of mitochondria in the middle sized muscle fibers after division of the sensory fibres are reported and discussed.
