1
Q

Where does the maxillary artery come from

A

it is a terminal branch of the external carotid artery

2
Q

Unique fact about the facial and lingual arteries

A

they often will share a trunk

3
Q

the two terminal branches of the external carotid artery are the

A

superficial temporal a. and the maxillary a.

4
Q

Three “parts” of the maxillary artery from lateral to more medial

A

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

5
Q

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

A

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
Q

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

A

Branches of the pterygopalatine portion of the maxillary artery include

A

Sphenopalatine
Descending (Greater) Palatine
Infraorbital
Pharyngeal
Post sup alveolar
Artery of pterygoid canal
10
Q

branches which arise from the infraorbital a.

A

nasal septal branches

11
Q

artery of the incisive canal

A

an anastomosis of the nasal and oral cavities

12
Q

an anastomosis of the nasal and oral cavities

A

artery of the incisive canal

13
Q

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

A

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

14
Q

terminal branch of the maxillary artery

A

sphenopalatine a

15
Q

The facial a is a branch of

A

the external carotid

16
Q

trace the path and branches of the facial a.

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
Q

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

A

from the ophthalmic artery which lies deep

18
Q

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

A

the infraorbital foramen

19
Q

Where does the buccal a. run

A

to the buccinator

20
Q

which artery is a termination of the inferior alveolar a.

A

the mental a.

21
Q

artery which will serve maxillary anterior dentition and the max sinus

A

the infraorbital

22
Q

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

A

the post. sup. alveolar a.

23
Q

a. which serves the hard and soft palates

A

descending palatine a.

24
Q

primary artery of the TMJ

A

deep auricular (also does stuff by the ear)

25
Q

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

A

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
Q

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

A

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
Q

buccinator muscle classification (hint: think about its innervation)

A

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
Q

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

A

inf. alveolar a.

29
Q

Major venous drainage of the face

A

external jugular vein

30
Q

The retromandibular vein is formed by

A

the maxillary and superficial temporal veins

31
Q

The facial vein receives blood superiorly from

A

the supraorbital and supratrochlear veins from the ophthalmic veins

32
Q

Clinical significance of the pterygoid plexus

A

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

33
Q

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

A

the retromandibular and the post. auricular

34
Q

which two veins come together to form the internal jugular vein

A

the retromandibular vein will join with the facial vein

35
Q

area which is considered the danger triangle

A

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