What is the function of the anterior facial vein?
The facial vein, also referred to as the anterior facial vein, is a paired vessel and the main vein of the face. The facial veins stem from the angular veins on each side of the root of the nose….Facial vein.

What forms the facial vein?
Veins of the head and neck. The facial vein usually unites with the anterior branch of the retromandibular vein to form the common facial vein, which crosses the external carotid artery and enters the internal jugular vein at a variable point below the hyoid bone.
Where does the facial vein drain?
internal jugular vein
The facial vein (along with the facial artery) pierces the deep investing fascia of the neck just below the border of the mandible where it unites with the anterior branch of the retromandibular vein to form the common facial vein, which empties into the internal jugular vein 1,2,3.
What is facial vein a branch of?
angular vein
The facial vein (previously known as the anterior facial vein) is the continuation of the angular vein and joins the anterior branch of the retromandibular vein to form the common facial vein 1-3.
What is emissary vein?
The emissary veins are valveless vessels which connect the superficial veins of the scalp with deeper veins, e.g. diploic veins of the skull bones.
Why are facial veins valveless?
Abstract. Background: The ophthalmic and facial veins are frequently stated to be devoid of valves, facilitating the spread of infection from the mid-face to the cavernous sinus. Methods: Twelve superior and eight inferior ophthalmic veins together with 13 angular and facial veins were harvested from adult cadavers.
What is ophthalmic vein?
The ophthalmic veins are the two vessels that drain the venous blood from the structures of the orbit into the cavernous sinus. Namely, they are the superior ophthalmic vein and the inferior ophthalmic vein, with the former being much larger than the latter.
Where is the anterior jugular vein?
The anterior jugular vein arises from the confluence of the superficial submandibular veins. Its origin is located near the hyoid bone, approximately 1 centimeter lateral to the midline of the neck.
Why is the jugular vein so important?
The function of the internal jugular vein is to collect blood from the skull, brain, superficial parts of the face, and the majority of the neck. The tributaries of the internal jugular include the inferior petrosal sinus, facial, lingual, pharyngeal, superior and middle thyroid, and, occasionally, the occipital vein.
What is the common facial vein?
The common facial vein drains from an area that corresponds more or less with the distribution of the facial, maxillary, and superficial temporal arteries. It originates from the intersection of the facial and retromandibular veins near the angle of the mandible.
What are Diploic and emissary veins?
Emissary, diploic, and meningeal veins Diploic veins form an interlacing channel through the diploic space, and again can act as emissary veins insofar as they can communicate the extracranial drainage with the dural sinuses. The meningeal veins drain the dura in roughly the distribution of the meningeal arteries.
What is the facial vein?
The facial vein, also referred to as the anterior facial vein, is a paired vessel and the main vein of the face. The facial veins stem from the angular veins on each side of the root of the nose.
What is the anterior vein of the nose?
Anatomical terminology. The facial vein (or anterior facial vein) is a relatively large vein in the human face. It commences at the side of the root of the nose and is a direct continuation of the angular vein where it also receives a small nasal branch.
What are the superficial arteries and veins of the face?
Superficial Arteries and Veins of the Face and Scalp 1 Facial Artery. The Facial artery is the 4th branch of the external carotid and branches off in… 2 Maxillary Artery Branches. The maxillary artery (the 7th branch of the external carotid)… 3 Veins of the Face. The facial vein is a large vessel of the face and is much less tortuous than…
What is the difference between the angular and facial veins?
The facial vein (previously known as the anterior facial vein) is the continuation of the angular vein and joins the anterior branch of the retromandibular vein to form the common facial vein 1-3. At the level of the lower margin of the orbit, the angular vein becomes the facial vein 1.
