Maxillary Artery Flashcards
1
Q
Beginning
A
- Inside parotid
- Opposite mandible neck
- Largest of 2 terminal branches of ECA
2
Q
Course
A
- Passes forward, medial, and upwards
- Reach Pterygopalatine fossa
- Ends by dividing into many branches
3
Q
End in 1st part
A
- Lies deep to mandible neck within parotid
- Passing horizontally from its origin till lateral pterygoid lower border
4
Q
2nd part end
A
- Passes obliquely superficial to lateral pterygoid lower head (sometimes deep to it)
5
Q
3rd part end
A
- Passes between lateral pterygoid 2 heads
- Then through pterygomaxillary fissure
- Reach Pterygopalatine fossa
6
Q
Branches of 1st part (5)
A
- Middle meningeal artery
- Accessory meningeal artery
- Inferior alveolar artery
- Anterior tympanic artery

- Buccal artery: face
8
Q
Branches 3rd part (6)
A
- Infraorbital artery
- Pharyngeal artery
- Pterygoid canal artery
- Greater palatine artery
- Posterior superior alveolar artery
9
Q
AMA and MMA course
A
- Pass deep to lateral pterygoid
- In front of MMA
- Enter middle cranial fossa via foramen ovale
10
Q
AMA supply
A
- Dura matter
- Trigeminal ganglion
11
Q
Inferior alveolar artery course
A
- Pass through Mandibular foramen inside Mandibular canal
- Ending opposite mental foramen by dividing into incisive and mental branches and mylohyoid artery descending in mylohyoid groove
12

Inferior alveolar artery supply
A
- Mandible
- Lower teeth
- Lower lip
13

Nasal cavity
19
Q
Greater palatine artery supply (4)
A
- Nasal septum
- Soft palate
- Palatine tonsil
- Hard palate
20
Q
Infraorbital artery course
A
- Pass through inferior orbital fissure
- Infraorbital groove
- Infraorbital canal
- Reach face through Infraorbital foramen
- Divides into nasal, palpebral, labial branches
Gives anterior superior alveolar artery in orbital canal
21
Q
Greater palatine artery course
A
- Passes through greater palatine canal and foramen
- Reach hard palate
- Passes through incisive canal
- Reach nasal septum
- Gives 2 lesser palatine arteries
22
Q
