Regeneration of nerves.
When a severed hand is reattached, how is the nerve restored? Do new
nerve
bodies form and grow new axons? Do the old axons rejoin their segments? Do
the
proximal parts of the old axons extend along the route of the nerve? How do
the new
nerves find the right places? Does the sensation starting at the thumb give
a
sensation associated with the thumb or is it random and the patient learns
how it
works?
