Question 1

According to the paper, there are four reasons why axonal regeneration after CNS injury is a failure. Name one reason.

Answer 1

lack of neurotrophic stimulation, absence of permissive substrates to support axonal attachment and extension through lesion site, presence of myelin and extracellular matrix-associated inhibitors in the injured site, potential deficiency of intrinsic gene expression to support active axonal state

Question 2

Which group showed the greatest amount of axonal growth beyond the lesion site?

Answer 2

CNN

Question 3

Which group (s) showed the greatest amount of axonal growth in the lesion site?

Answer 3

CNN and PNN

Question 4

there was a significant functional differences observed among lesioned groups.

Answer 4

False

Question 5

combination of somal stimulation by NT-3 and axonal stimulation by cAMP gradient promotes axonal bridging in the spinal cord lesion site and inhibitory area of adult white matter.

Answer 5

False
