For a peripheral nerve fiber to regenerate, it is crucial to have the neurosoma (the cell body of the neuron) and at least some part of the neurilemma (the outermost layer of the Schwann cells that wrap around the axon of the neuron) intact. The neurosoma contains the nucleus and the necessary cellular machinery for the neuron's survival and regeneration, while the neurilemma plays a key role in regeneration by providing a pathway for the growth of the axon.
