Fine structure of normal and degenerating motor axons and nerve-muscle synapses in the locust,Schistocerca gregaria

Aspects of turnover and biogenesis of synaptic vesicles at locust neuromuscular junctions as revealed by zinc iodide-osmium tetroxide (ZIO) reacting with intravesicular SH-groups.

“…The final branching of the two motor axons and the general morphology of the synapses closely resemble the pattern described for Schistocerca (50): The electron-transparent synaptic vesicles are often scattered over the whole cross-sectional area of the nerve terminal, but tend to be more frequent near the junctions ( Fig. 1).…”

Degenerative and regenerative processes involved in midgut pseudotumor formation in the stick insect (Carausius morosus)

“…Remarkably, not all severed nerves degenerated at the same time. The pathological characteristics of the nerve degradation resembled closely that of degenerating motor axons in the desert locust (Rees and Usherwood, 1972). The electron microscopic examination showed that 5 days after ganglion ectomy many nerves were still intact.…”

The sensitivity to glutamate of denervated muscles of the crayfish

“…Anatomically, various stages of degenerating nerve terminals were seen following denervation. The progressive stages appear to be very similar in appearance, although slower in time course, to those seen in degenerating neuromuscular contacts in amphibians (Birks et al 1960), mammals (Miledi & Slater, 1968), and insects (Rees & Usherwood, 1973). After 4 months the nerve terminals had completely disappeared.…”
