However, the supporting connective tissue structures including the endoneurial tubes, perineurium and epineurium, are still intact. Axonotmesis is the term used when there is complete interruption of the nerve axon and its myelin sheath, but the mesenchymal structures including perineurium and epineurium are either completely or partially intact. The next level is called axonotmesis, which involves direct damage to the axons in addition to focal demyelination while maintaining continuity of the nerve's connective tissues. This type of nerve injury is caused by a crush or pressure damage. Axonotmesis: se define por una discontinuidad axonal y una degeneración axonal distal y una regeneración axonal proximal.
