Endoneurium
Endoneurium
Endoneurium (pronounced: en-doh-noor-ee-uhm) is a layer of delicate connective tissue that surrounds individual nerve fibers within a peripheral nerve. It is derived from the Greek words "endon" meaning within, and "neuron" meaning nerve.
Etymology
The term "Endoneurium" is derived from two Greek words: "endon", which means 'within', and "neuron", which means 'nerve'. Thus, the term literally translates to 'within the nerve'.
Structure
The endoneurium is the innermost layer of connective tissue around a nerve fiber. It is composed of collagen and elastin fibers, and is responsible for providing both support and nutrition to the nerve fibers. It also plays a crucial role in the repair and regeneration of damaged nerve fibers.
Function
The primary function of the endoneurium is to protect and support individual nerve fibers within a nerve. It provides a barrier against foreign substances, and also helps in the maintenance of the blood-nerve barrier, which is crucial for the proper functioning of the nerves.
