C. M3 cell bodies are near the ventral g1 duct openings into the lumen.
D. Pharyngeal nerve ring is composed of the circumferential neuron processes.
E-J. Consecutive sections through the first bulb show the trajectories of M2 and M3 processes piercing pm4 to reach the dorsal cord. (Image source: N2W [MRC] prints C-J 93, 80, 52, 51, 49, 40, 39, 33.)
