Answer:
Endonerium
Explanation:
The endoneurium (also called endoneurial channel, endoneurial sheath, endoneurial tube, or Henle's sheath) is a layer of delicate connective tissue around the myelin sheath of each myelinated nerve fiber in the peripheral nervous system. Its component cells are called endoneurial cells.The endoneuria with their enclosed nerve fibers are bundled into groups called nerve fascicles, each fascicle within its own protective sheath called a perineurium. In sufficiently large nerves multiple fascicles, each with its blood supply and fatty tissue, may be bundled within yet another sheath, the epineurium.
ANSWERS:
They are both ionic compounds.
These compounds are made up of 
cations (positively-charged ion) and either 
or 
anions (negatively-charged ions).
Their names both end in -ic acid.
Acids are named based on their anion. With acids like these where the anion is attached to a hydrogen cation, we name such acids with the the suffix “-ic”.
They both contain polyatomic ionic.
and are both polyatomic ions.
"Poly-" = many
"ions" = have a + or - charge
So, yes, these are ions that are made up of several atoms (not just one atom like )
