Morphometric comparison between contralateral sciatic nerves in the male and female rabbit

Anat Histol Embryol. 1997 Jun;26(2):147-50. doi: 10.1111/j.1439-0264.1997.tb00115.x.

Abstract

Some morphometrical parameters of the axons making up the contralateral sciatic nerves, both in the male and female rabbits were calculated and compared by means of a Zeiss Vidas image analyser (Ober Kochen, Germany). The results show that the fibres constituting the left nerve have a greater mean diameter but a lower mean density that those constitution the right nerve. This suggests that the diameter of the myelinated fibres and the density of both the myelinated and unmyelinated fibres do not vary from male to female. On the other hand, the G ratio and the diameter of the unmyelinated axons do, since the nerves on the right side (in both sexes) have higher morphometric values, on average, than the contralateral ones.
