Abstract

Schistocerca gregaria possess four neurones of giant fibre proportions within the abdominal ventral nerve cord. These fibres arise from single cell bodies in the terminal ganglionic mass and pass without interruption to the metathoracic ganglion. Fibres become reduced in diameter when passing through a ganglion. Branching of the giant fibres occurs in abdominal ganglia 6 and 7.

Résumé

Schistocerca gregaria possède quatre neurones de type géant dans la chaîne nerveuse ventrale abdominale. Ces fibres proviennent de cellules individuelles de la masse ganglionique terminale et passent sans interruption au ganglion mitathoracique. Le diamitre de ces fibres est réduit lorsqu’ils passent a travers un ganglion. Les fibres géants branchent dans le sixième ainsi que le septième ganglion abdominal.
