maxillary artery Flashcards
order of arteries branching out UPWARD
- deep auricular
- anterior tympanic
- middle meningeal
- accessory meningeal
- masseteric
- deep temporal
order of arteries branching out DOWNWARDS
- IAN
- pterygoid branches
- buccal
- posterior superior alveolar
maxillary a originates in
the substance of parotid gland
maxillary a supplies
- nasal cavity
- roof and lateral wall of oral cavity (cheeks)
- teeth and gingiva
- chin
- dura of cranial cavity
three parts of max artery
- mandibular
- pterygoid
- pterygopalatine
mandibular part of max artery gives rise to
- deep auricular
- anterior tympanic
- middle meningeal
- accessory meningeal
- IAA
deep auricular supplies
- EAM
- lateral aspect of tympanic membrane
- TMJ
deep auricular a travels with
auriculotemporal n
anterior tympanic a supplies
- mucosa of the middle ear
- internal aspect of tympanic membrane
anterior tympanic a travels with
chorda tympani n
middle meningeal a passes through which n roots
auriculotemporal n
middle meningeal a supplies
- dura matter
- inner table of bone and diploe of cranial vault
middle meningeal a passes through what to enter the skull
foramen spinosum
accessory meningeal a supplements supply of what a
middle meningeal a
IAA gives off a branch
branch to mylohyoid (companion to mylohyoid n)
IAA supplies
-lower molars and 2nd premolar
IAA branches into
- incisive branch
- mental branch
incisive branch supplies
-lower incisors, canine, 1st pm
mental branch supplies
- chin
- lower lip
- gingiva of incisors - 2nd premolar
deep temporal aa
travel with deep temporal nn and supply temporalis m
pterygoid branch supplies
medial and lateral pterygoid mm
masseteric a pass through
mandibular notch (sigmoid notch)
masseteric a supplies
masseter m and TMJ
buccal a path
- down with buccal n
- pierces temporalis m tendon and travels along buccinator m
buccal a supplies
- skin, m, and oral mucosa of cheek
- vestibular gingiva of molar teeth (md)
posterior superior alveolar a (PSA) supplies
- max premolar and molar teeth
- adjacent gingiva
- mucosal lining of max sinus
infraorbital a leaves the pterygopalatine fossa through
inferior orbital fissure
anterior superior alveolar a is a branch of
infraorbital a
what does anterior superior alveolar a supply
- max incisors, canines
- adjacent gingiva
- mucosa of anterior wall of max sinus
infraorbital a branches into
- inferior palpebral
- lateral nasal
- superior labial
inferior palpebral branch
lower eyelid
lateral nasal branch
lateral nose
superior labial branch
upper lip
descending palatine a travels with
palatine n
descending palatine a branches into
greater and lesser palatine aa
lesser palatine branch supplies
soft palate
greater palatine a supplies
- hard palate
- gingiva of max teeth from 1st pm -molars
greater palatine a anastomoses with
-nasopalatine a
sphenopalatine a companion
nasal n
sphenopalatine a supplies
-lateral and medial wall of nasal cavity
nasopalatine a supplies
palatal mucosa and gingiva of anterior max teeth
pharyngeal a supplies
- nasopharynx
- sphenoidal sinus
- pharyngotympanic tube
artery of pterygoid canal supplies
- nasopharynx
- pharyngotympanic tube
- middle ear
pterygoid venus plexus is found
between temporalis and pterygoid mm
pterygoid venus plexus connects anteriorly to
facial v (via deep facial v)
pterygoid venus plexus connects posteriorly to
retromandibular v (via the short max v)
