Seddon's classification is a scheme for describing nerve injury.

1. Neurapraxia -- temporary paralysis of a nerve caused by lack of blood flow or by pressure on the affected nerve with no loss of structural continuity.
2. Axonotmesis -- neural tube intact, but axons are disrupted. These nerves are likely to recover.
3. Neurotmesis -- the neural tube is severed. These injuries are likely permanent without repair, and will likely only achieve partial recovery at best.
