Study Notes
Oral Anatomy Lecture: Arteries & Veins
- Plexus: A large network of blood vessels
- Anastomosis: A connecting channel between blood vessels for communication.
- Artery: Carries blood away from the heart, branching into arterioles and then capillaries.
- Vein: Carries blood back to the heart. In the head and neck, few valves allow two-way blood flow, which may be relevant for dental infections.
- Venous Sinus: Blood-filled space between two tissue layers.
Ascending Aorta
- Blood leaving the left ventricle enters the ascending aorta (oxygenated).
- The aorta branches to the brachiocephalic artery (then right common carotid), and left common carotid directly.
Common Carotid Artery Division
- Internal Carotid Artery: Enters the brain via the carotid canal, receiving blood from the vertebral arteries. Supplies the brain (intracranial structures) and the eye, orbit, and lacrimal gland, as well as the ophthalmic artery.
- External Carotid Artery: Branches off at the lower border of the posterior belly of the digastric muscle, supporting cranial/facial structures. It branches into anterior and posterior sections, which further subdivide into specific branches supplying distinct areas: superior thyroid artery, lingual artery, facial artery, occipital artery, posterior auricular artery, ascending pharyngeal artery, maxillary artery, and superficial temporal artery.
Facial Artery
- Part of the external carotid artery.
- Supplies skin of the face.
- Branches into ascending palatine (soft palate, palatine muscles, tonsils), and submental (submandibular lymph nodes and salivary glands) arteries.
- Travels through the submandibular notch and into the face.
Maxillary Artery
- Terminal branch of external carotid.
- Supplies skin of the face, as well as some specified areas such as the temporal region, and facial expression muscles.
Important Veins
- Internal Jugular Vein: Drains blood in the head and neck, and receives blood from the pterygoid plexus.
- External Jugular Vein: Drains blood from behind the ear.
- Posterior Superior Alveolar Vein: Drains the pulp tissue of max teeth/periodontium (including gingiva).
- Inferior Alveolar Vein: Drains the pulp tissue of mand teeth/periodontium (including gingiva.)
- Cavernous Sinus: A significant venous structure supporting the spread of infections. It's located near the base of the brain
