Proximodistal gradient in endoneurial fluid pressure.
Endoneurial fluid pressure measurements were made in the interstitial space of rat L5 dorsal root ganglia and in the corresponding sciatic nerves. Endoneurial fluid pressure was always higher in the ganglia than in the paired distal nerve. This proximodistal gradient in endoneurial fluid pressure may be the driving force responsible for the proximodistal convection of endoneurial fluid.
