Structure/Morphology

The epineurial arteries are located in the external epineurium and form part of the vasa nervorum, small blood vessels that supply nourishment to the peripheral nerves. This network of vessels supplies blood to the interior parts of the nerves and their coverings. The vasa nervorum are located within the connective tissue of the nerve scattered between the fascicles (Boissaud-Cooke, Pidgeon and Tunstall, 2015).

Anatomical Relations

The vasa nervorum are the smallest vessels in the epineurial, perineurial, and endoneurial layers.

Function

The vasa nervorum supply the peripheral nerves with the molecular nutrients needed to carry out their cellular functions and for survival (Carp, 2015).
