Definition

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.

Common questions about Blood-Nerve Barrier

What does Blood-Nerve Barrier mean in medicine?
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. This definition is taken from the National Library of Medicine's MeSH (Medical Subject Headings) 2026 release, which is the standard vocabulary used to index PubMed and most medical literature.
Is Blood-Nerve Barrier known by any other names?
