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

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 |
