Examples synaptic terminals on TTMNs that illustrate the synaptic vesicles. The vesicles contained in the terminal in A are large and round (Lg Rnd), those in the terminal in B are smaller and round (Sm Rnd), and those in the terminal in C are pleomorphic (Pleo). As illustrated, our criteria for synapses requires a cleft between pre- and postsynaptic membrane (arrowheads), postsynaptic dense material, and synaptic vesicles. The terminal in B has a dense core vesicle (DCV). The terminal in C is associated with a TTMN spine (sp), curved in this case, and seen in two parts as it invaginates the terminal. Scale bar = 0.5 μm.
