epineurium
Physiology
(noun)
The outermost layer of dense, irregular connective
tissue surrounding a peripheral nerve.
Biology
Examples of epineurium in the following topics:
-
Structure of a Nerve
- Finally, the entire nerve is wrapped in a layer of connective tissue called the epineurium.
- An illustration of a cross-section of a nerve highlighting the epineurium and perineurium.
-
Axon Bundles
- Each nerve consisting of many fascicles is covered externally by a dense sheath of connective tissue, the epineurium.
-
Optic (II) Nerve
- The optic nerve is ensheathed in all three meningeal layers (dura, arachnoid, and pia mater) rather than the epineurium, perineurium, and endoneurium found in the peripheral nerves.
-
Injuries to Nerves Emerging from the Brachial Plexus
- The epineurium of the nerve is contiguous with the dura mater, providing extra support to the nerve.
-
Thermoreception
- End-bulbs are found in the conjunctiva of the eye, in the mucous membrane of the lips and tongue, and in the epineurium of nerve trunks.
