Photomicrographs of transverse sections of the gastrocnemius muscle following denervation and subsequent reinnervation.

<p>The muscle sections of (A) immediate repair, (B) chronic denervation with sensory protection and (C) chronic denervation with mixed-nerve protection showed wide areas of larger muscle fibers among small groups of atrophied fibers. (D) Unprotected muscle sections showed extensive atrophy. Magnification×100. Scale bar= 100µm.
