What is the typical rate of axonal regrowth in a regenerating human peripheral nerve?
Show answer and explanation
Correct answer: 1 to 2 mm per day
Axonal regeneration typically proceeds at a rate of approximately 1 to 2 mm per day. This rate is limited by the slow component of axonal transport, which moves structural proteins like actin and tubulin.
