maxillary art branches Flashcards
Deep auricular artery 1st part
-pierces the bony and cartilageous part of the external acoustic meatus
- supplies external ear, tympanic membrane & TMJ
Anterior tympanic artery. 1st part
-enters the tympanic cavity through the pterygotympanic fissure
- supplies the middle ear and tympanic membrane
Middle meningeal artery 1st part
enters the cranial cavity through the foramen spinosum
-supplies the dura mater.
Accessory meningeal artery 1st part
enters through foramen ovale – supplies the meninges & infratemporal fossa
Inferior alveolar artery 1st part
enters mandibular foramen – supplies the lower jaw and chin
2nd part
- Deep temporal artery
*Pterygoid branches - Masseteric artery
- Buccal artery
Before entering into the Pterygomaxillary fissure
- Infraorbital artery
- Posterior superior alveolar artery
- Infraorbital artery
Infraorbital artery
enters orbit via inferior orbital fissure, runs in infra orbital canal & emerges through infra orbital foramen.
Gives anterior superior alveolar artery
-supplies lacrimal sac, nose and upper lip
Posterior superior alveolar artery
enters through foramina on the posterior surface of the maxilla
- supplies upper molar, premolar teeth and maxillary air sinus
Within Pterygopalatine fossa:
Greater palatine artery
Pharyngeal artery
Artery of pterygoid canal
Greater palatine artery
enters greater palatine canal passes through the greater palatine foramen and then incisive canal. Supplies palate and gums, lesser palatine branch.
Pharyngeal artery
supplies nasopharynx, auditory tube and sphenoidal air sinus.
Artery of pterygoid canal
supplies pharynx, auditory tube and middle ear
Terminal branch:
Sphenopalatine artery
leaves through the sphenopalatine foramen and divides into posterolateral nasal , posterior septal branches
-supplies the nasal cavity
