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

27

Infraorbital artery

Supplies upper lip, lower eyelid , end of max artery, gingiva next to ant. teeth, side of nose
