COMMON CAROTID ARTERY

-Bifurcates into...
3. Bifurcates into the internal and external carotid arteries at the superior
border ofthe thyroid cartilage; the carotid body, a tiny vascular struc-
ture within the angle formed by the internal and external carotid arter-
ies, is a sensor ofthe oxygen content ofthe blood and is innervated by
sensory branches from the glossopharyngeal and vagus nerves
INTERNAL CAROTID ARTERY
B. Internal carotid artery: ascends in the carotid sheath medial to the internal
jugular vein and enters the skull through the carotid canal to supply the
brain; it has no branches in the neck
EXTERNAL CAROTID ARTERY

-Ascends anterior to the...
C. External carotid artery

1. Ascends anterior to the internal carotid artery; its branches are noted
below
EXTERNAL CAROTID ARTERY

SUPERIOR THYROID ARTERY
C. External carotid artery

2. Superior thyroid artery: arises inferior to the tip ofthe greater cornu of
the hyoid, descends with the external laryngeal nerve deep to the sterno-
thyroid, and supplies the thyroid gland; gives rise to the superior laryn-
geal artery which penetrates the thyrohyoid membrane with the inter-
nal laryngeal nerve
EXTERNAL CAROTID ARTERY

ASCENDING PHARYNGEAL ARTERY
C. External carotid artery

3. Ascending pharyngeal artery: slender branch arising from the medial
side ofthe external carotid artery; ascends between the internal carotid
artery and lateral wall ofthe pharynx
EXTERNAL CAROTID ARTERY

LINGUAL ARTERY
C. External carotid artery

4. Lingual artery: arises posterior to the tip ofthe greater cornu ofthe hyoid;
ascends deep to the posterior belly ofthe digastric and submandibular
gland
EXTERNAL CAROTID ARTERY

OCCIPITAL ARTERY

-arises from the posterior...
C. External carotid artery

5. Occipital artery

a. Arises from the posterior side of the external carotid artery, oppo-
site the origin of the lingual artery; the hypoglossal nerve hooks
around its branch to the sternocleidomastoid
EXTERNAL CAROTID ARTERY

OCCIPITAL ARTERY

-ascends posteriorly...
C. External carotid artery

5. Occipital artery

b. Ascends posteriorly, deep to the posterior belly ofthe digastric and
within the groove for the occipital artery, medial to the mastoid
process; traverses the superior part of the posterior triangle of the
neck and emerges through the trapezius inferolateral to the exter-
nal occipital protuberance
EXTERNAL CAROTID ARTERY

FACIAL ARTERY

-arises superior to the tip...
C. External carotid artery

6. Facial artery

a. Arises superior to the tip ofthe greater cornu ofthe hyoid; courses
deep to the submandibular gland and gives rise to the branches noted
below
EXTERNAL CAROTID ARTERY

FACIAL ARTERY

ASCENDING PALATINE ARTERY
C. External carotid artery

6. Facial artery

b. Ascending palatine artery: ascends deep to the medial pterygoid on
the lateral aspect ofthe superior pharyngeal constrictor; arches over the superior border of the superior pharyngeal constrictor and de-
scends to the soft palate
