“…INSERT FIGURE 1 ABOUT HERE Developmentally, the trigeminal nerve is well formed in utero (Gasser and Hendrickx, 1969;Hogg, 1941). Indeed, the perioral areas supplied by the mandibular and maxillary divisions are the first embryonic regions to respond to cutaneous stimulation (circa 7.5 weeks).…”

“…At this time during development, we were able to trace nerve fibers in a comparably sized specimen (Stage 20,19 mm) to the basement membrane throughout the tongue dorsum. Hogg (1941) reported that cutaneous fibers in the maxillary nerve in a 25 mm embryo terminated 5 m from the basement membrane of the epithelium in the face. During the same period (20 -27 mm), however, Humphrey (1965) was unable to find any nerve fibers entering the dental papillae that are the primordia of teeth.…”

To determine in selected, staged human embryos the time period and manner of formation of the sensory nerves to the mucosa on the dorsum of the tongue, cranial nerves V(3) and IX and their lingual branches were traced microscopically. These two cranial nerves along with cranial nerve VII are present in the dorsal part of their respective pharyngeal arch 1, 2, and 3 at Stage 13. All three nerves grow ventrally at Stage 16, and the lingual branches of V(3) and IX become closer to the developing tongue region. The lingual fibers begin to enter the tongue substance at Stage 17 when they appear as large short branches that terminate 100-400 microm from the dorsal mucosal basement membrane; of the fibers that are in the tissue deep to the surface mucosa, those in the posterior tongue segment terminate the closest and those in the anterior segment the farthest. Chorda tympani nerve fibers are joined with V(3) at Stage 20. At this stage nerve fibers reach the basement membrane in the posterior tongue segment and by Stage 23 they terminate at the basement membrane throughout the tongue, being sparsest in the anterior segment. Primordial papillae appear as small mucosal projections throughout the tongue at Stage 20 and are innervated by Stage 23. The study found that innervation to the dorsum of the tongue develops during the second month of prenatal life. During the 4-week period, Stages 13-23, an innervation pattern was observed based on the relative time fibers terminate at the basement membrane. The pattern begins caudally in the root, then moves rostrally lateral to the middle tongue segment, proceeding then to the tip of the tongue. The last area to become innervated is the medial part of the middle segment or central portion of the tongue.
