Flashcards in The Maxillary Artery and its branches Deck (35):
1

Where does the maxillary artery come from

it is a terminal branch of the external carotid artery

2

Unique fact about the facial and lingual arteries

they often will share a trunk

3

the two terminal branches of the external carotid artery are the

superficial temporal a. and the maxillary a.

4

Three "parts" of the maxillary artery from lateral to more medial

the mandibular part (most lateral), the pterygoid part, and the pterygopalatine part

5

Compare the 3 parts of the maxillary artery in location to the lateral pterygoid muscle

the mandibular part is proximal to the lateral pterygoid
the pterygoid part is adjacent to it
the pterygopalatine part is just distal to the muscle

6

From lateral to more medial, what are the branches of the maxillary artery

Infraorbital
Pharyngeal
Post sup alveolar
Artery of pterygoid canal

10

branches which arise from the infraorbital a.

nasal septal branches

11

artery of the incisive canal

an anastomosis of the nasal and oral cavities

12

an anastomosis of the nasal and oral cavities

artery of the incisive canal

13

the descending palatine a. branches of the maxillary a., runs inf., and gives off which arteries? What do these arteries then do

The descending palatine gives off the greater and lesser palatine arteries which loop ant. to meet the artery of the incisive canal (anastomosis)

14

terminal branch of the maxillary artery

sphenopalatine a

15

The facial a is a branch of

the external carotid

16

trace the path and branches of the facial a.

the facial a. runs sup towards the mouth where it will give off two branches which run horizontally (the sup and inf. labial branches running above and below the mouth) the facial a. then continues sup towards the nose where it gives rise to another more horizontally directed a. called the lateral nasal a.

The artery continues sup as the angular a. running ant to and inf to the eye

17

the supratrochlear and supraorbital arteries of the face arise from which structure(s)

from the ophthalmic artery which lies deep

18

Which hole in the face does the infraorbital a. run through?

the infraorbital foramen

19

Where does the buccal a. run

to the buccinator

20

which artery is a termination of the inferior alveolar a.

the mental a.

21

artery which will serve maxillary anterior dentition and the max sinus

the infraorbital

22

Artery which serves the maxillary molars and premolars, as well as the max sinus

the post. sup. alveolar a.

23

a. which serves the hard and soft palates

descending palatine a.

24

primary artery of the TMJ

deep auricular (also does stuff by the ear)

25

Foramen which the middle meningeal a. passes through and the significance

the foramen spinosum and then through the pterion which is easily fractured. This serves blood to the dura mater as well as the trigeminal ganglion so a fracture to the pterion can be troublesome

26

Explain why if someone fractures their pterion they may lose function of their muscles of mastication

the trigeminal ganglion is fed blood by the middle meningeal a. which passes through/near the pterion. I do not know what this would actually cause, it is more of a thought question

27

buccinator muscle classification (hint: think about its innervation)

innervated by the buccal n. which is a branch of CNVII, thus it is a muscle of facial expression... Although, it does help in mastication!

28

artery which serves the mandibular teeth, chin, and mylohyoid m.

inf. alveolar a.

29

Major venous drainage of the face

external jugular vein

30

The retromandibular vein is formed by

the maxillary and superficial temporal veins

31

The facial vein receives blood superiorly from

the supraorbital and supratrochlear veins from the ophthalmic veins

32

Clinical significance of the pterygoid plexus

it directly communicates with the cavernous sinus thus can access the brain and is a threat for disease spread

33

what two veins will come together to form the external jugular vein

the retromandibular and the post. auricular

34

which two veins come together to form the internal jugular vein

the retromandibular vein will join with the facial vein

35

area which is considered the danger triangle

from the corners of the mouth to the bridge of the nose
