accessory pharyngeal nerve [FBbt_00004024]

The ~5um thick accessory pharyngeal nerve of the adult brain (Miller, 1950 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 pharyngeal nerve in at their exit point from the gnathal ganglion, probably from the mandibular neuromere (Ito et al., 2014, but penetrate at a lower level into the space between the anterior cibarial plate and the dilator muscles. From here, the nerve enters the labrum to connect with its muscles and sense organs. (Miller, 1950, Ito et al., 2014)
