perineurium造句

• The organ is surrounded by a dense, perineurium-like connective tissue.
• The epineurium and perineurium remain intact, thus preventing the formation of stump neuroma.
• The perineurium is a smooth, transparent tubular membrane which may be easily separated from the fibers it encloses.
• He found that the current of injury runs through the perineurium  through the myelin sheaths of the peripheral nerves.
• This is surrounded by perineurium and epineurium, of which the latter is the outmost layer of dense connective tissue.
• In third-degree injury, there is a lesion of the endoneurium, but the epineurium and perineurium remain intact.
• The perineurium is composed of connective tissue, which has a distinctly lamellar arrangement consisting of roughly seven to eight concentric layers.
• The endoneurium runs longitudinally along the nerve fiber, but with discontinuities where septa pass inward from the innermost layer of the perineurium.
• The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium.
• The axon and myelin sheath are affected, but all of the connective tissues ( endoneurium, perineurium, and epineurium ) remain intact.
• The optic nerve is ensheathed in all three arachnoid, and pia mater ) rather than the epineurium, perineurium, and endoneurium found in peripheral nerves.
• The perineurium is cellular, and is composed of perineurial cells, which are epithelioid and myofibroblastoid properties including tight junctions, gap junctions, external laminae and contractility.
• Axonotmesis involves loss of the relative continuity of the axon and its covering of myelin, but preservation of the connective tissue framework of the nerve ( the encapsulating tissue, the epineurium and perineurium, are preserved ).
• The deep fasciae envelop all bone ( periosteum and endosteum ); cartilage ( perichondrium ), and blood vessels ( tunica externa ) and become specialized in muscles ( epimysium, perimysium, and endomysium ) and nerves ( epineurium, perineurium, and endoneurium ).
