Inputs to the DC and VC motoneurons. A schematic summary diagram, data from somites 1 and 2 in a 12-day B. floridae larva, showing synaptic inputs (arrows and terminals with vesicles) and contacts via JR junctions (parallel lines) to the dorsal compartment (DC) and ventral compartment (VC) motoneurons. Other neurons: third pair of large paired neurons (LPN3), ipsilateral projection neurons (IPN), type 2 preinfundibular projection neurons (PPN2). The tegmental neuropile (tn) is a region where paracrine transmission predominates. Neurons colored orange are cholinergic, as in Fig. 2e. Modified from [10]
