Tripartite interaction of perisynaptic glial processes with pre- and postsynaptic elements is a shared feature of several different adult neuromuscular synapses.

Confocal immunofluorescence images of neuromuscular synapses as described in Fig 1. Fine terminal axon branches making synaptic contacts on coxal muscles in the leg (A-C) and the tergotrochanteral muscle (TTM) in the thorax (D-F) exhibit close association with glial processes as observed at DLM neuromuscular synapses.
