Figure 1.
Photomicrographs of femoral motor and sensory nerve cross-sections. The fresh motor nerve (A) has larger diameter, but, fewer fibers in comparison to the fresh sensory nerve (B). These larger endoneurial tubes may mechanically provide a more favorable size conduit for nerve regeneration than the smaller sensory endoneurial tube. Comparisons between fresh motor (A) and cold motor (C) or fresh sensory (B) and cold sensory (D) nerves demonstrate the small amount of shrinkage that takes place during the cold preservation procedure.
