A clinical study involving patients with traumatic injuries to extremities is conducted. Some of these patients had transection of a peripheral nerve trunk. It is observed that axonal and myelin sheath degeneration occurs in the nerve trunk distal to the site of injury. In many of these patients, motor function is regained in the affected extremity. Which of the following cells is most important in regaining function following nerve injury?
A Macrophage
B Microglial cell
C Neuroblast
D Oligodendrocyte
E Satellite cell
F Schwann cell

plus oligodendrocytes mylinates CNS and CN2 which once damaged cant regenreate,eg in MS

i thought it was F....periphral Nervous system?
E - is for muscles, These cells are involved in the normal growth of muscle, as well as regeneration following injury or disease.

hmm..ok the answer is FF.... Wallerian degeneration typically occurs following traumatic transection of the axon. If the transected nerve is realigned and the basement membrane is not lost, then the nerve can regrow back to the synapse. Schwann cells will remyelinate the axon.
