Where does the maxillary artery come from
it is a terminal branch of the external carotid artery
Unique fact about the facial and lingual arteries
they often will share a trunk
the two terminal branches of the external carotid artery are the
superficial temporal a. and the maxillary a.
Three “parts” of the maxillary artery from lateral to more medial
the mandibular part (most lateral), the pterygoid part, and the pterygopalatine part
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
From lateral to more medial, what are the branches of the maxillary artery

Sphenopalatine Descending (Greater) Palatine Infraorbital Pharyngeal Post sup alveolar Artery of pterygoid canal
branches which arise from the infraorbital a.
nasal septal branches
artery of the incisive canal
an anastomosis of the nasal and oral cavities
an anastomosis of the nasal and oral cavities
artery of the incisive canal
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)
terminal branch of the maxillary artery
sphenopalatine a
The facial a is a branch of
the external carotid
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
the supratrochlear and supraorbital arteries of the face arise from which structure(s)
from the ophthalmic artery which lies deep
Which hole in the face does the infraorbital a. run through?
the infraorbital foramen
Where does the buccal a. run
to the buccinator
which artery is a termination of the inferior alveolar a.
the mental a.
artery which will serve maxillary anterior dentition and the max sinus
the infraorbital
Artery which serves the maxillary molars and premolars, as well as the max sinus
the post. sup. alveolar a.
a. which serves the hard and soft palates
descending palatine a.
primary artery of the TMJ
deep auricular (also does stuff by the ear)
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
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
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!
artery which serves the mandibular teeth, chin, and mylohyoid m.
inf. alveolar a.
Major venous drainage of the face
external jugular vein
The retromandibular vein is formed by
the maxillary and superficial temporal veins
The facial vein receives blood superiorly from
the supraorbital and supratrochlear veins from the ophthalmic veins
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
what two veins will come together to form the external jugular vein
the retromandibular and the post. auricular
which two veins come together to form the internal jugular vein
the retromandibular vein will join with the facial vein
area which is considered the danger triangle
from the corners of the mouth to the bridge of the nose
