what connective tissue sheath surrounds the fascicle of a nerve?
Peripheral nerves have three layers of connective tissue: Epineurium â is the outermost layer of connective tissue that is continuous with the dura mater. It also includes the connective tissue in between any fascicles (bundles) within the nerve. Perineurium â is the connective tissue sheath that surrounds a fascicle of axons. Endoneurium â is the delicate connective tissue fibers that surround individual axons. Subspecialty
