Implication

Microscopic examination reveals that neurotubules are not part of intact nerve axons, suggesting a different role in nerve structure.

Key Points

  • The study aims to clarify the relationship between fibrous structures in nerve axons and the localization of neurotubules.
  • Examined nerve sections from squid, frog, rat, and human using an electron microscope.
  • Analyzed the filament structure and localization within axons and surrounding connective tissue.
  • Compared thin sections and formalin-fixed preparations to identify the presence of neurotubules.
  • Identified characteristic filaments in axons with diameters of 100 to 200 A.
  • Found neurotubules primarily in the connective tissue sheath rather than in axons.
  • Evidence does not support neurotubules as integral to normal intact nerve structure.
