Common carotid ascends in a sheath with IJV and vagus n. to superior thyroid cartilage | |
Divides here into Internal and External | |
Carotid sinus: baroreceptor | |
Carotid body: chemoreceptor | |
Vessels | |
Internal Carotid | |
No branching in the neck | |
Enter skull via carotid foramina | |
Main arteries of brain and orbital structures | |

Vessels | |
External Carotid | |
Six main branches: | |
Superior Thyroid | |
Ascending pharyngeal | |
Lingual | |
Facial | |
Occipital | |
Posterior Auricular | |
Ascends to parotid gland/neck of mandible, divides into maxillary and superficial temporal arteries | |
Veins | |
Internal Juglar Vein | |
Largest vein in neck | |
Drains blood from brain, anterior face/neck | |
Tributaries are veins that primarily accompany arteries | |
Superior Bulb | |
Enlargement near skull | |
Inferior Bulb | |
Has bicuspid valve that allows blood to flow | |
towards heart without backflow |
