| what are the divisions of the trigeminal nerve | V1 - opthalmic nerve V2 - maxillary nerve V3 - mandibular nerve |
| what does the opthalmic nerve exit through | superior orbital fissure |
| what does the opthalmic nerve innervate | eye, forehead, ethmoid sinus, sphenoid sinus, frontal sinus, medial part of nose |
| what does the maxillary nerve exit through | foramen rotundem into pterygopalatine fossa, all remaning branches branch from there |
| the maxillary nerve innervates what | upper jaw and cheek |
| (branches from max) the zygomatic nerve has what two branches | zygomatico-temporal nerve, zygomatico-facial nerve |
| (branches from max) the zygomatic nerve exits through | inferior orbital fissure into the zygomatic bone through the zygomatico-orbital foramen. branches from there. |
| the zygomatico-temporal nerve exits and innervates what | exits through the zygomatico-temporal foramen. supplies skin over anterior fourth of temporalis muscle |
| the zygomatico-facial nerve exits and innervates what | exits through the zygomatico-facial foramen. innervates skin overlying lateral surface of zygoma |
| lesser palatine nerves exit through and supply what | exit through lesser palatine foramen. supplies palatine tonsils and soft palate. |
| grater palatine nerve exits through and supplies what | exits through greater palatine foramen. supplies posterior 2/3 of hard palate and palatal gingiva of area. |
| the posterior inferior lateral nasal nerves exit and supply what | exit off greater palatine nerve. supply mucosa of inferior nasal concha, middle and inferior meati |
| nasopalatine nerve exits and innervates | exits through sphenopalatine foramen. innervates septal mucosa, palatal mucosa, palatal gingiva on anterior 1/3 of hard palate. may supply max. central incisors. |
| posterior superior lateral nasal nerves exits and innervates | exits medially through sphenopalatine foramen. supplys mucosa of middle and superior nasal conchae and superior part of nasal septum. |
| posterior suprerior alveolar nerves exit and innervate | branches off max in pterygopalatine fossa, descends through pterygomaxillary fissure into maxilla through posterior superior alveolar foramina. innervates max molars (not mesiobuccal root of 1st), buccal gingiva & mucosa of same area, mucosa of max sinus |
| infraorbital nerve exits | exits onto face through infraorbital foramen. |
| middle superior alveolar nerves supplies | max premolars, mesiobuccal root of max 1st molar, buccal gingiva and buccal mucosa of same area, mucosa of max sinus |
| anterior superior alveolar nerve supplies | max anterior teeth, labial gingiva and mucosa of max sinus. |
