Definition of neurilemma in English:



  • The thin sheath around a nerve axon (including myelin where this is present).

    • ‘When an axon is cut the neurilemma forms a regeneration tube.’
    • ‘The neurilemma of a medullated fibre contains myelin laid down by Schwann cells.’
    • ‘The oligodendrocyte does not form a neurilemma because its cell body does not wrap around any axons.’
    • ‘The axis cylinder is the essential conducting structure of the nerve, while the neurolemma and the myelin act as insulating agents.’
    • ‘These nuclei are believed to be in connection with a delicate sheath corresponding with the neurolemma of the medullated nerve fiber.’
