Adult Nervous system Neuron projection bundle

A nerve that arises from the lateroposterior side of the mesothoracic neuromere at a point anterior to the root of the haltere nerve (Power, 1948; Court et al., 2020. It extends posteriorly and slightly dorsally and laterally, around the anterior wings of the mesofurca, before branching (Power, 1948; Court et al., 2020. One branch innervates the furcoentopleural muscles (muscles 59 and 60) and the other innervates laterally placed muscles, anterior to the halteres (Power, 1948; Court et al., 2020.
