Conversation

Have you ever heard of the term epineurium?

No, I haven't. What does it mean?

It's actually the thick sheath of connective tissue that surrounds a nerve trunk.

Oh, that sounds interesting! I didn't know nerves had such protective layers.

Root Explanation

Epineurium → It is formed from "epi-" (meaning upon or over) and "neurium" (from Greek "neuron", meaning nerve). The word refers to the connective tissue that surrounds and protects nerves, literally meaning the layer that is over the nerve.

Memory Tip

Think of a protective layer that is 'upon' ('epi-') the 'nerve' ('neurium') — that's what epineurium means.
