English: Rotation of a three-dimensional reconstruction of the aCC motor neuron and surroundings at late stage 16. Expression of the membrane marker myr-tdTom driven by the elav-Gal4 promoter shows sensory and motor neurons in the region of muscles 3, 2 and 1. The aCC motor neuron traverses the anterior fascicle along with the RP2 neuron. Both continue in parallel past the chordotonal neurons and a cluster of dorsal sensory neurons. The RP2 neuron forms a synapse with muscle 2 just above the dorsal sensory neurons while the aCC neuron continues growing for approximately 30 more µm until it synapses with muscle 1. This final stage of elongation of a singular growth cone was used for live in vivo imaging. Scale bar = 20 µm.
