Fig. 6a Diagram of architectures of single nerve bundle.
Each nerve bundle surrounded by the dense irregular
connective tissue (epineurium), subdividing into perineurium
that enclosed nerve fasciculi. Each fasciculi is composed of
numerous nerves fibers that surrounded by the loose
connective tissues (endoneurium).

location of epineurim and perineurium.
