Abstract:
A comparative description is given of fine structure of adult and fifth instar hopper's abdominal nerves of locust, Locusta migratoria migratorioides. Hoppers nerves contain fewer axons per cross- sectional area of nerve than adult nerves, with the result that in nerves of equal diameter the hoppers nerves large fluid-filled spaces are interposed between the Schawann cell layers. Small such spaces are found in adult nerves. The physiological significance of differences in axon numbers and sheath structure is discussed. Some of the dissimilarities in Schwann cell structure may be accounted for by the assumption that hopper nerves are more resistant to mechanical deformation than nerves of adult locust.
