Summary
The fine structure of synapses, their distribution and arrangement in the ventral nerve cord of Peripatoides leuckarti (phylum Onychophora) is described. The asymmetric synaptic junctions show a well developed synaptic cleft (300Å) and pre- and subsynaptic electron dense apposition. They frequently show an array of presynaptic projections and a subsynaptic cisterna of endoplasmic reticulum. The onychophoran synapses differ from those of annelids and insects.
