Axonotmesis includes discontinuity in: (A) Perineurium, (B) Epineurium, (C) Endoneurium, (D) Axon
Answer is D. Axonotmesis is a disruption of nerve cell axon, with Wallerian degeneration occurring below and slightly proximal to the site of injury. If axons and their myelin sheath are damaged, but Schwann cells, the endoneurium, perineurium and epineurium remain intact, it is called axonotmesis.
