Pre- and post-synapse exhibit perfect complementarity in young adult NMJs. (A,B) Pre-synaptic terminal as represented by motoneuronal markers for synaptic vesicles [synaptophysin (A)] and neuronal cytoskeleton [neurofilament (B)]. (C) Post-synaptic apparatus contains large amounts of AChRs directly juxtaposed to pre-synaptic ACh filled synaptic vesicles. (D) Overlay of synaptophysin (red), neurofilament (green), and AChR stainings (blue) nicely shows the perfect complementarity of pre- and post-synaptic portions of NMJ.
