The pharyngeal nerve, 7um thick, arises from the subesophageal ganglion close to, or fused with, the accessory pharyngeal nerve at its extreme base. After branching to the cibarial sense organ, it loops beneath muscle 9 near the cibarial-esophageal junction to anastomose medially with the stomodeal nerve and the contralateral pharyngeal nerve. From the region of these anastomoses a single median nerve extends ventrally and gives a number of branches to the dilator muscle of the cibarial pump (Miller, 1950).
