1
Brachiocephakuc artery
Branches off aorta on right side and goes to head
2
Right common carotid artery comes off of what?
Brachiocephalic
3
L common carotid artery comes off of what?
Aorta
4
What does the common carotid run with?
The internal jugular vein and vagus nerve through the carotid sheath
5
Common carotid divides at larynx (2) types:
External carotid
Internal carotid: skull before it branches
6
What are the branches of the external carotid?
Superior thyroid
Lingual
Facial
Ascending pharyngeal
Occipital
Posterior auricular
Maxillary
Superficial temporal
7
Facial artery
Side of the neck deep to submandibular gland crosses lower border of mandible in front of angle of mand. (Pressure pt. for bleeding) travels across face and ends near inner corner of the eye as the angular artery
8
Lingual artery
Branches off below facial artery and goes beneath hypoglossus muscle and ends in 3 branches: dorsal lingual/deep lingual/sublingual
9
Dorsal lingual
Deep post. tongue
10
Deep lingual
Deep ant. tongue
11
Sublingual
Ventral surface of tongue and floor of the mouth
12
Linguofacial trunk
Lingual/facial arteries come off as one trunk from external carotid and then split
13
Max superficial temporal artery are terminal branches of external carotid.
-SUPPLIES: muscles of mastication/ teeth / oral and nasal cavities/ coverings of the brain.
MAXILLARY ARTERY
14
Veins along infra-temporal fossa crosses what?
The lateral pterygoid muscles and enters pterygopalatine fossa (behind/below eye)
15
Branches of the maxillary artery:
Infratemporal fossa branches
Pterygopalatine fossa branches
16
What are the infratemporal fossa branches?
Inferior alveolar branch
Temporal branch
Massetric branch
Pterygoid branch
Middle meningeal artery
Buccal branch
17
Enters the mandible at the mandibular foramen. Supplies teeth and bone. Branches in premolar region to become mental artery and incisive artery.
Inferior alveolar branch
18
Mental artery
Leaves mandible through the mental foramen. It supplies buccal gingiva, lower lip, and mucosa over teeth.
19
Two branches of temporal branch??
Anterior deep temporal artery and posterior deep temporal artery
20
Massetric branch
Runs through coronoid notch to masseter muscle
21
Middle meningeal artery
Opposite (IA)
Through foramen spinosum ( major blood supply to meninges of brain)
22
Buccal Branch
Supplies mucosa of cheeks and mucosa of max n mand post. teeth
23
5 directions of the pterygopalatine fossa branches:
Back- nasal pharynx
Down- palate
Medial- nasal cavity
Lateral- max. tuberosity
Forward- infraorbital area
24
Descending palatine artery
Enters hard palate via pterygopalatine canal. 2 branches : lesser/ grater palatine
25
Posterior superior alveolar artery (PSA)
Enters via pterygomaxillary fissure. Enters bone behind 3rd max molars
26
Pterygopalatine artery
Enters via sphenopalatine foramen
Supplies nasal cavity
Emerges from incisive foramen and joing greater palatine
