› First-degree: A reversible local conduction block at the site of the injury.

› Second-degree injury: There is a loss of continuity of the axons or electrical wires within the nerve.

› Third-degree injury: There is damage to the axons and their supporting structures within the nerve.

› Fourth-degree injury: In this case, there is damage to the axons and the surrounding tissues sufficient to create scarring that prevents nerve regeneration.

› Fifth-degree injury: These injuries are usually found in laceration or severe stretch injuries.
