Specific paucity of unmyelinated C-fibers in cutaneous peripheral nerves of the African naked-mole rat: comparative analysis using six species of Bathyergidae.

In considering the data by species, rather than by nerve, there is a clear trend in all species other than the naked mole-rat for saphenous and sural nerves to have much higher C:A-fiber ratios than in mixed and muscle nerves (∼3:1 compared with ∼1.5:1 in common peroneal and tibial, ∼1:1 lateral gastrocnemius, and ∼0.5:1 for medial gastrocnemius).
