Neurotmesis interferes with ____________________.

• A. Nerve conduction only
• B. Axonal transport only
• C. Neither axonal transport nor nerve conduction
• D. Both axonal transport and nerve conduction

Answer: (D)

Neurotmesis disrupts both the ability of impulses to travel along the nerve and the internal transport system that moves materials along the axon. When the nerve is completely cut, including its protective connective tissue, conduction can no longer propagate beyond the injury because the physical path for the electrical signal is broken. At the same time, axonal transport—the process that shuttles enzymes, organelles, and other essential cargo between the cell body and distal parts of the axon—is interrupted at the cut, so distant segments cannot receive these materials and begin to degenerate. This combination makes neurotmesis the most severe nerve injury, with poor spontaneous recovery unless surgical repair re-establishes continuity and a pathway for axon regeneration.
