<P> Each nerve is a cordlike structure containing bundles of axons . Within a nerve , each axon is surrounded by a layer of connective tissue called the endoneurium . The axons are bundled together into groups called fascicles , and each fascicle is wrapped in a layer of connective tissue called the perineurium . Finally , the entire nerve is wrapped in a layer of connective tissue called the epineurium . </P>
