Supplies blood to posterior tongue, tonsils and, soft palate

Supplies blood to inferior tongue and apex (anterior tip) of tongue)

Supplies skin and muscles of facial expression (such as areas around the mouth, around orbit, etc)

Arches anteriorly and superiorly, this artery crosses the inferior border of the mandible, a pulse can be felt (covered by platysma and skin)

Terminates as angular artery which is at base of nose and medial corner of eye

Branches off at mandible

Arises slightly superior or at the same level as the facial artery

Supplies sternocleidomastoid muscle, deep muscles of neck and, posterior part of scalp

Supplies tympanic cavity, outer ear, adjacent scalp

Ascends through parotid, felt across zygomatic arch

Supplies parotid gland, masseter muscle, external ear, TMJ and scalp to superior ear

Mandibular

(medial to neck of condyle)

Pterygoid (in infratemporal fossa)

Regions (formed in pterygopalatine fossa)

Arises at level of neck of condyle (passes medial condyle between neck and sphenomandibular ligament

Now crosses the infratemporal fossa then enters the pterygopalatine flsssa

Emerges onto face via infraorbital foramen

Supplies:

Maxillary and mandibular teeth and jaws

Muscles of mastication

palate

part of nasal cavity

Dura mater

parts of ears

Veins

Facial Vein

Retromandibular vein

Major drainage of face

begins medial to eye as angular vein

Connects with

Mental Artery

Mylohyoid artery

Nasopalatine artery

Posterior Superior Artery

(PSA)

Descending Palatine Artery

Greater Palatine Artery

Infraorbital artery

Lesser Palatine Artery

MSA

ASA

Supplies sublingual and submandibular gland. lymph nodes in area, mylohyoid and digastric muscles

Runs inferior and superior to lips, supplies lips

Supplies blood to skin of muscles in nose

Supplies blood to tissues around the orbit

Angular artery has an anastomoses with the opthalmic artery og the internal carotid

THIS IS 1 BRACH OF THE EXTERNAL CAROTID THAT IS PRIMARILY INTRACRANIAL

Runs in area of infra. fossa

Supplies: the Buccinator and main muscles of mastication (masseter, temporalis, medial and later pterygoid)

Pterygopalatine (in its fossa)

Supplies lingual gingiva of man.

Runs inside Man canal

Direct continuation of IAa, runs in man canal

Supplies skin of chin and mucous membrane of lower lip

Facial gingiva from mental foramen to midline

Travels medially along mandible to midline

Supplies: mylohyoid muscle

Supply maxillae, max teeth, nasal cavity and palate

ORGINATED MEDIAL TO infratemporal fossa

leaves pterygopalatine fossa by way of pterygomaxillary fissure, descends on the posterior surface of max and enters

Supplies: Max Posterior teeth (except mesiobuccal)

BUCCAL gingiva

Begins in fossa, moves anteriorly through the infraorbital canal and emerges out foramen

Supplies: Lower eyelid, cheek, upper lip and lateral nose

Arterial branch of infraorbital artery, given off in the Infraorbital canal

Supplies: mesiobuccal root of 3&14 amd premolars (PDLS and roots and alveolar bone)

FACIAL gingiva

ARTERIAL BRANCH OF INFRAORBITAL Artery. More anteriorly MSA

Supplies: Max anterior teeth

FACIAL ginigval

ASA, MSA and PSA are all in anastomose with eachother.

L + R ASA anastomose with itself at the midline

Runs inf in greater and lesser palatine canals

Supplies:

LINGUAL gingiva adjacent to max POSTERIOR teeth

POSTERIOR hard palate

Supplies:

Soft palate and palatine tonsil

Begins in pterygopalatine foosa, medially through sphenopalatine foramen, medially to nasal septum, on septum anteriorly and inferiorly, emerges out nasopalatine/incisive foramen

Supplies:

LINGUAL gingiva of Max anteriors

Anterior hard palate

Off carotid @ superior border of thyroid cartilage, enters skull thry carotid canal, travels and ascends above foramen Lacerum to lesser wing of sphenoid

Reaches brain by turning sup +post to anterior clinoid process

NO BRANCHES GIVEN OFF AT NECK

Vertebral artery

Follows cervical vertebrae superiorly

Enters cranial vault but foramen Magnum

Vertebral Artery (info on other side)

Basilar Artery

Supplies various areas of the Brain

Joining of L&R vertebral arteries

Basliar artery connects the INTERAL CAROTID ARTERIES AND VERTEBRAL ARTERIES IN the CIRCLE OF WILLIS

located at the base of the brain near the sella turcia

anastomoses- allows for equalization of blood supply to the brain
