    Study Notes

    Blood Supply to the Head and Neck - Arterial Supply

    • The arterial supply to the head and neck is complex
    • Key arteries include the internal and external carotid arteries.
    • The external carotid artery supplies the majority of the face
    • Important branches of the external carotid include:
      • Superior thyroid artery (thyroid gland, neck and larynx)
      • Ascending pharyngeal (pharynx, soft palate and prevertebral muscles)
      • Lingual artery (tongue, sublingual gland, buccal/gingival mucous membranes)
        • Further splits into sublingual, dorsal lingual, and deep lingual branches
      • Facial artery (muscles and skin of the face, submandibular gland)
      • Occipital artery (muscles in the posterior neck, skin of the neck and ear, scalp)
      • Posterior auricular artery (muscles in the posterior neck, skin over and around the ear, ear structures)
      • Superficial temporal artery (skin and muscles of the scalp, parotid gland, temporomandibular joint)
      • Maxillary artery (maxilla, mandible, nasal cavity and deep facial areas, important structures in the head and face)
        • Supplies the teeth - superior, middle and posterior alveolar branches
    • The internal carotid artery supplies the brain, eyes, forehead and part of the nose..
    • The vertebral arteries supply blood to the spinal cord and vertebral muscles.
    • The arch of the aorta gives rise to the brachiocephalic, left common carotid, and right subclavian arteries.
    • The left common carotid artery comes directly from the arch of the aorta.
    • The right common carotid arises from the brachiocephalic artery.
    • These arteries branch to supply both sides of the head and neck in a mirrored fashion.
    • Using mnemonics can aid in remembering the branches and their functions.

    GDC Learning Outcomes

    • Describe relevant dental, oral, craniofacial and general anatomy, applying knowledge to patient management.
