A loose connective tissue sheath surrounding each peripheral nerve. Composed mainly of colagen and fibroblasts, it forms a substantial covering over nerve trunks, then thins to an incomplete layer around smaller branches near their terminations. The epineurium is continuous centrally with the dura. Peripherally, it usually ends near the termination of a nerve fiber, but it may continue as the capsule of Meissner corpuscles and a few other encapsulated endings. Nolte, J.

outermost layer of connective tissue surrounding a peripheral nerve. It includes the blood vessels supplying the nerve. It consists of adipose tissue and fibrocollagenous tissues[Wikipedia:Epineurium].
