Study Notes
Arterial Blood Supply of the Head and Neck
- The arterial blood supply of the head and neck originates from the aortic arch, which gives rise to three main vessels: the brachiocephalic, left common carotid, and right subclavian arteries.
- The brachiocephalic trunk branches into the right subclavian and right common carotid arteries.
- The right subclavian artery supplies the right vertebral artery.
- The right common carotid artery bifurcates into the internal and external carotid arteries.
- The left common carotid and left subclavian arteries originate directly from the aortic arch.
- The left subclavian artery supplies the left vertebral artery.
- The external carotid artery branches into eight main arteries: superior thyroid, ascending pharyngeal, lingual, facial, occipital, posterior auricular, superficial temporal, and maxillary.
Branches of the External Carotid Artery
- Superior Thyroid: Supplies the thyroid gland, some neck muscles, and the larynx.
- Ascending Pharyngeal: Supplies the pharynx, soft palate, and prevertebral muscles.
- Lingual: Supplies the base of the tongue, the palatoglossal arch, the tonsils, the soft palate, the epiglottis, the sublingual gland, the muscles of the floor of the mouth, and the buccal and gingival mucous membranes.
- The lingual artery branches into the dorsal lingual, deep lingual, and sublingual arteries.
- Facial: Supplies muscles and skin of the face, and the submandibular gland.
- Occipital: Supplies muscles in the posterior neck, skin of the neck and ear, and the scalp in the occipital region.
- Posterior Auricular: Supplies muscles in the posterior neck, skin over and around the ear, and ear structures.
- Superficial Temporal: Supplies some skin and muscles of the scalp, parotid gland, and temporomandibular joint.
- Maxillary: Supplies the teeth and other structures of the upper jaw.
- The maxillary artery branches into the inferior alveolar, descending palatine, and superior alveolar arteries.
- The inferior alveolar artery branches into the dental, incisive, and mental arteries.
Key Learning Points
- The arterial supply to the head and neck is complex.
- The internal and external carotid arteries are the two main bilateral vessels supplying the head and neck.
- The external carotid artery supplies most of the mouth and the face.
- The key branches of the external carotid artery for dental work are the lingual, facial, and maxillary arteries.
- You need to have an awareness of other branches, as well as the importance of using a mnemonic to remember them.
