Note the location of the three pairs of openings where the three branches of the trigeminal nerve leave the brain: the superior orbital fissure for the ophthalmic branch, the foramen rotundum for the maxillary branch, and the foramen ovale for the mandibular branch. This branch innervates the soft tissue of the plus provides sensory branches to the pulp of all maxil- nasal septum and gingiva and palatal soft tissue lingual lary teeth. After passing through nerves combined with the greater palatine nerves inner- the foramen rotundum, the maxillary nerve passes vate the soft tissue of the entire hard palate (shown as into the pterygopalatine space and eventually splits into all red lines in Fig. Once within the trabecular nerve, passes through the greater palatine foramen to (spongy) bone of the maxilla and the maxillary sinus, its become the greater palatine nerve. Human skull: inferior surface including the palate, showing the foramina for branches of the trigeminal nerve that innervates the mucosa of the palate: the greater palatine foramen (for the greater palatine nerve) and the incisive foramen (for the nasopalatine nerve). The more posterior red lines indicate the diagrammatic distribution of the branches of the greater palatine nerves as they spread out along the junction of the alveolar processes with the palatine processes of the maxillae to the tissues (mucosa) of the palate located between the posterior teeth. The more anterior red lines indicate the nasopalatine nerve branches spreading out to the mucosa between the anterior teeth. It (apical foramina) to supply the maxillary premolars also innervates the supporting alveolar bone, periodon- (and the mesiobuccal root of the maxillary first molar), tal ligaments, and facial gingiva next to the maxillary supporting alveolar bone, periodontal ligaments, and molars, the mucosa of part of the maxillary sinus, and facial gingiva in the maxillary premolar region and part cheek mucosa next to maxillary molars. It is important to realize that the nerve supplying primary teeth is the same as that to the permanent teeth that replace them.

Maxillary division of the trigeminal nerve: branches that innervate the maxillary teeth. The lateral wall of the left maxilla has been removed exposing the large maxillary sinus. Another branch, the infraorbital nerve, passes from the pterygopalatine space to the floor of the eye orbit (which also forms the roof of the maxillary sinus) where it enters the infraorbital canal (not shown). Within the infraorbital canal, two branches split off to pass downward along the walls of the maxillary sinus and into the maxilla. The infraorbital branch continues through the infraorbital canal to exit the maxilla through the infraorbital foramen, which provides feeling to the skin on the side of the nose, the anterior part of the cheek, and the upper lip on that side. After exiting from the infraorbital foramen, the infraorbital nerve splits into its end (terminal) branches 3.

Mandibular division of the trigeminal nerve branches (yellow) : The external wall of the right mandible has been removed to expose the inferior alveolar nerve within the mandible, where it gives off the many small branches to each mandibular tooth. One branch, the mental nerve, exits through the mental foramen to innervate the skin of the chin and lip on that side, while the other branch is really a continuation of the inferior alveolar nerve anteriorly within the man- dible where it is called the incisive nerve (not visible here). Also, note the other major branches of the mandibular division: the lingual nerve, which is in close proximity to the inferior alveolar nerve posteriorly, but then diverges anteriorly to enter the tongue; and the buccal nerve, which innervates the cheek and tissue next to mandibular molars. Other nerve branches (not shaded) are motor branches of the mandibular nerve supplying the muscles of mastication. Location of the branches of the mandibular division of the trigeminal nerve (mandibular nerve) (in red): As the man- dibular nerve passes through the infratemporal space, it gives off the buccal nerve to the cheek (lateral to the ramus). Before entering the mandibular foramen, the mandibular nerve (medial to the ramus) gives off a lingual nerve branch that passes to the tongue. The inferior alveolar nerve enters the mandibular foramen (and canal) where it and its terminal incisal branch give off branches through the spongy bone to all mandibular teeth.
