Blood-Nerve Barrier

The barrier between the perineurium of PERIPHERAL NERVES and the endothelium (ENDOTHELIUM, VASCULAR) of endoneurial CAPILLARIES. The perineurium acts as a diffusion barrier, but ion permeability at the blood-nerve barrier is still higher than at the BLOOD-BRAIN BARRIER.

Abstract

The barrier between the perineurium of PERIPHERAL NERVES and the endothelium (ENDOTHELIUM, VASCULAR) of endoneurial CAPILLARIES. The perineurium acts as a diffusion barrier, but ion permeability at the blood-nerve barrier is still higher than at the BLOOD-BRAIN BARRIER.
