adult pharyngeal nerve

ID: FBbt_00004021

The pharyngeal nerve of the adult brain is 7um thick and contains axons connecting with the lower, anterior half of the adult head capsule including sensory organs along the esophagus (Ito et al., 2014). It fuses with the accessory pharyngeal nerve at its exit from the gnathal ganglion, probably from the mandibular neuromere (Ito et al., 2014). After branching to the cibarial sense organ, it loops beneath cibarial 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).
