TRIGEMINAL NERVE
MAXILLARY NERVE POSTERIOR SUPERIOR MEDIAL NASAL NERVES |
3. Posterior superior medial nasal nerves and their largest branch, the
nasopalatine nerve a. Enter the nasal cavity through the sphenopalatine foramen and sup- ply the posterosuperior, posteroinferior, and anteroinferior parts of the nasal septum b. The nasopalatine nerve descends anteriorly on the nasal septum, and then passes through the incisive canal and incisive fossa to provide sensory innervation to the hard palate posterior to the upper incisors |

TRIGEMINAL NERVE
MAXILLARY NERVE GREATER PALATINE NERVE |
4. Greater palatine nerve
a. Descends in the greater palatine canal and emerges from the greater palatine foramen; it then courses anteriorly, supplying the hard pal- ate up to the incisor teeth b. As it descends in the inferior part of the greater palatine canal, it gives off posterior inferior lateral nasal nerves that supply the postero- inferior part of the lateral nasal wall |

TRIGEMINAL NERVE
MAXILLARY NERVE LESSER PALATINE NERVES |
5. Lesser palatine nerves: descend in the greater palatine canal and emerge
through the lesser palatine foramina to supply the soft palate |
|
|
TRIGEMINAL NERVE
MAXILLARY NERVE POSTERIOR SUPERIOR ALVEOLAR NERVE |
6. Posterior superior alveolar nerve: its branches enter the alveolar
foramina on the infratemporal surface of the maxilla and supply the upper molars |
|
|
TRIGEMINAL NERVE
MAXILLARY NERVE INFRAORBITAL NERVE |
7. Infraorbital nerve
a. Enters the orbit through the inferior orbital fissure and courses for- ward in the infraorbital groove; as it continues forward in the infra- orbital canal, it gives off the middle superior alveolar and anterior superior alveolar nerves 7. Middle superior alveolar nerve: descends within the lateral wall of the maxillary sinus and supplies the upper premolars 2. Anterior superior alveolar nerve: arises from the infraorbital nerve just before it emerges from the infraorbital foramen; descends within the anterior wall of the maxillary sinus and supplies the upper canine and incisors b. Emerges onto the face through the infraorbital foramen to supply the lower eyelid, side of the nose, upper lip, and the skin overlying the anterior surface of the maxilla |
