Figure 10.

Intersegmental contacts between MNs. A, A reconstructed image of ssTEM of the CNS of a first instar (white line meshes). A pair of RP2 motor neurons in the A1 segment (green) and RP3 motor neurons in the neighboring A2 segment (purple) are studied. B, An enlarged view of the neurites of the two pairs of MNs shown in A, showing intersegmental contacts (arrows). Ci–Civ, Electromicroscopic images of the intersegmental contacts indicated by arrows in B. Neurites of the MNs are depicted by corresponding colored asterisks (purple and green). Scale bar, 100 nm.
