. Cunningham's Text-book of anatomy. Anatomy. MAXILLAEY NEKVE. 777 is the terminal branch of the maxillary nerve, which enters the orbit through the inferior orbital fissure and traverses the infra-orbital canal to reach the face. In the infra-orbital canal the infra-orbital nerve supplies one and sometimes two branches to the teethâ-the middle and anterior superior alveolar nerves (ramus alveolaris superior medius et rami alveolares superiores anteriores). The former may be only a secondary branch of the latter nerves, or they may arise independently from the infra-orbital nerve. However formed, the nerves descend in bony canals in the wall of the maxillary sinus (to the lining of which branches are given), and reach the alveolar arch, where they form minute plexuses and supply the teeth (joining posteriorly with the branches of the posterior superior alveolar nerve). The anterior superior alveolar nerve supplies the incisor and canine teeth; the middle superior alveolar nerve supplies the premolar teeth. After emerging on the face from the infra-orbital foramen, the infra-orbital nerve divides into a number of radiating branches arranged in three setsâ{a) Zygomatic branch at inferior orbital fissure Maxillary nerve at foramen rotundum Infra-orbital nerve appearing on the face at the infra-orbitalâ foramen Middle and anterior / alveolar branches \.

These branches form com- munications with the zygomatic branches of the facial nerve, and give rise to the infra-orbital plexus (Fig. 657, p. 783).
