Morphology

endoneurium = neuron (opaque) = endo + neur + ium

The term is specialized and not directly transparent to learners without medical knowledge.

Etymology

The word endoneurium comes from three parts: endo- meaning 'inside', neur- meaning 'nerve', and -ium a common ending for 'tissue' or 'parts'. So endoneurium is the tissue 'inside' a nerve that wraps and protects each tiny nerve fiber.
