Type 3 nerve injury is characterized by what?

Explanation:
Type 3 nerve injury is characterized by axonotmesis with disruption of the endoneurial tubes while the perineurium remains intact. This means the axon and its myelin are damaged and distal degeneration occurs, but the protective fascicular coverings are still present to guide some axonal regrowth. It’s distinct from conduction block or demyelination (neuropraxia) and from a complete nerve transection (neurotmesis). The preserved scaffolding means recovery is possible, though more limited than when endoneurial structures are intact.
