Fig. 12. Fine structure of a synapse from a tonic receptor of the gymnotid
Eigenmanniu. A short process from the receptor cell ( R ) invaginates into the nerve
terminal ( N ) . A presynaptic dense body ( D ) extends into the synaptic process.
There are numerous presynaptic vesicles ( V ) . From Szamier and Wachtel ( 1969).
