Place the steps involved in the repair of a peripheral nerve in order from beginning to end.
1. axon sends buds into network of schwann cells and then starts growing along cord of schwann cells.
2. fragmentation of axon and myelin occurs in distal stump.
3. axon continues to grow into distal stump and is enfolded by schwann cells.
4. schwann cells form cord, grow into cut, and unite stumps.
5. macrophages engulf degenerating axon and myelin.
