Study Notes
Blood Supply to the Head and Neck - Arterial Supply
- The main artery supplying the head and neck is the aortic arch.
- The aortic arch branches into the brachiocephalic trunk, left common carotid, and left subclavian.
- The brachiocephalic trunk branches into the right subclavian and right common carotid arteries.
- Both the right and left common carotid arteries branch into the:
- internal carotid artery
- external carotid artery
- The internal carotid artery supplies:
- brain
- eyes
- forehead
- part of the nose
- The external carotid artery supplies:
- neck
- face
- scalp
- tongue
- maxilla
External Carotid Artery Branches
- The external carotid artery branches into several arteries, including:
- occipital artery
- posterior auricular artery
- superficial temporal artery
- maxillary artery
Occipital Artery
- The occipital artery supplies:
- muscles of the posterior neck
- skin of the neck and ear
- scalp in the occipital region
Posterior Auricular Artery
- The posterior auricular artery supplies:
- muscles of the posterior neck
- skin over and around the ear
- ear structures
Superficial Temporal Artery
- The superficial temporal artery supplies:
- some of the skin and muscles of the scalp
- parotid gland
- temporomandibular joint
Maxillary Artery
- The maxillary artery is one of the two terminal branches of the external carotid artery (along with the superficial temporal artery).
- It supplies:
- the whole maxillofacial region
- hard and soft tissues of the maxilla
- mandible
- nasal cavity
- deep facial areas
Maxillary Artery and the Teeth
- The maxillary artery supplies the teeth through the superior alveolar artery and the inferior alveolar artery.
- The superior alveolar artery branches into posterior, middle, and anterior branches, supplying maxillary teeth.
- The inferior alveolar artery branches into:
- dental branch
- incisive branch
- mental artery
- These inferior alveolar artery branches supply mandibular teeth.
Summary and Caveats
- Blood supply of the head and neck can be complex.
- Two main bilateral vessels are relevant to dentistry: internal and external carotid arteries.
- The external carotid artery branches are most relevant to dentistry.
- Key external carotid artery branches include: lingual, facial, and maxillary arteries.
- Anatomical variations exist; not everyone's vessels connect in the same way.
