There are three of these cells with very similar innervation patterns within the ventral nerve cord. The neuron projects dorsally, then branches laterally in both directions to form a T-shape. Ramifications are mostly found in the lateral neuropil of T1 and the posterior subesophageal ganglion. It also innervates the anterior part of T2 with dorsomedial bifurcations. Generally, two of these neurons (tVUM1sn) project via the segmental nerve with the other projecting via the intersegmental nerve (tVUM1isn), but this is sometimes the opposite way (Selcho et al., 2012). Innervation pattern has not been studied, so it is unclear how the three subclasses differ and whether they belong to the dorsal, lateral and ventral groups identified for abdominal neurons.
