Study Notes

Blood Supply to the Head and Neck - Arterial Supply

The arterial supply to the head and neck is complex.
Clinicians need to know the blood supply to avoid important vessels.
Knowledge of the blood supply is vital to understand normal variations.
The major arteries originate from the arch of the aorta.
The brachiocephalic artery, left common carotid, and right subclavian arteries arise from the arch of the aorta.
The left common carotid artery arises directly from the arch of the aorta.
The right common carotid artery arises from the brachiocephalic artery.
The right subclavian artery also arises from the brachiocephalic artery.
The right and left vertebral arteries supply the spinal cord and vertebral muscles.
The common carotid arteries split into the internal and external carotid arteries.
The internal carotid artery supplies the brain, eyes, forehead and part of the nose.
The external carotid artery supplies the superficial structures of the head and neck.
The external carotid artery branches into 8 main branches.
These branches are: superior thyroid, ascending pharyngeal, lingual, facial, occipital, posterior auricular, superficial temporal, and maxillary.
Each branch has a specific supply area.
For example, the superior thyroid branch supplies the thyroid gland, muscles in the neck, and larynx.
The lingual artery has three branches: dorsal lingual, sublingual, and deep lingual.
The lingual artery supplies the base of the tongue, palatoglossal arch, tonsils, soft palate, and epiglottis.
The sublingual artery supplies the sublingual gland, muscles in the floor of the mouth, and buccal/gingival mucous membranes.
The deep lingual artery supplies the body of the tongue.
The facial artery supplies the muscles and skin of the face and submandibular gland.
The occipital artery supplies muscles in the posterior neck, skin of the neck and ear, and scalp in the occipital region.
The posterior auricular artery supplies muscles in the posterior neck, skin over and around the ear, and ear structures.
The superficial temporal artery supplies skin and muscles of the scalp, parotid gland, and temporomandibular joint.
The maxillary artery supplies important structures of the maxillofacial region, including the maxilla, mandible, nasal cavity, and deep facial areas.
The maxillary artery also supplies all the teeth through several branches.
The internal and external carotid arteries are bilateral, supplying both sides of the head and neck.
Students need to learn the mnemonics for the 8 branches of the external carotid artery.

GDC Learning Outcomes

Dental and oral anatomy is important for patient management.
Students need to describe relevant anatomy, including craniofacial and general anatomy, along with its application in patient management.

Intended Learning Outcomes

Students will be able to identify the main arteries in the head and neck.
Students will be able to explain the distribution areas of those main arteries.
Students will be able to describe the connections and branches of the common carotid artery.
Students will be able to describe the connections and branches of the external carotid artery.

How to Learn

Memorize the structure through visual aids and diagrams
Create mnemonics and flashcards for easy memorization.
Use resources like diagrams, books, websites, and videos.

Where to Start

Begin with the basic anatomy of the arch of the aorta to understand the vessels of origin.
