What does the facial vein drain?

The facial vein (latin: vena facialis) is a blood vessel that is a continuation of the angular vein. Then the facial vein joins with the retromandibular vein to form the common facial vein, which drains into the internal jugular vein.

Furthermore, what forms the facial vein?

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.

Similarly, what is the venous drainage? In human anatomy, the systemic venous system refers to veins that drain into the right atrium without passing through two vascular beds (i.e. they originate from a set of capillaries and do not pass through a second set of capillaries before reaching the right side of the heart.

Also to know is, what does the Retromandibular vein drain into?

It divides into two branches: an anterior, which passes forward and joins anterior facial vein, to form the common facial vein, which then drains into the internal jugular vein. a posterior, which is joined by the posterior auricular vein and becomes the external jugular vein.

Which veins drain blood from the face scalp and neck?

Jugular vein. Jugular vein, any of several veins of the neck that drain blood from the brain, face, and neck, returning it to the heart via the superior vena cava. The main vessels are the external jugular vein and the interior jugular vein.

What is the dangerous area of the face?

There is a certain area in the face that is known as the danger area. Danger area consists of the area from the angle of mouth to the bridge of nose including the nose and maxilla.

What is the vein in your forehead called?

The frontal vein (supratrochlear vein) begins on the forehead in a venous plexus which communicates with the frontal branches of the superficial temporal vein. The veins converge to form a single trunk, which runs downward near the middle line of the forehead parallel with the vein of the opposite side.

Why are facial veins not tortuous?

The facial vein (anterior facial vein) commences at the side of the root of the nose, and is a direct continuation of the angular vein. It lies behind the external maxillary (facial) artery and follows a less tortuous course. The facial vein has no valves, and its walls are not so flaccid as most superficial veins.

Where is the facial nerve located?

The nerves typically travels from the pons through the facial canal in the temporal bone and exits the skull at the stylomastoid foramen. It arises from the brainstem from an area posterior to the cranial nerve VI (abducens nerve) and anterior to cranial nerve VIII (vestibulocochlear nerve).

Where is the pterygoid plexus of veins located?

Pterygoid plexus. Veins of the head and neck. The pterygoid plexus (/ˈt?r?g??d/; from Greek pteryx, "wing" and eidos, "shape") is a venous plexus of considerable size, and is situated between the temporalis muscle and lateral pterygoid muscle, and partly between the two pterygoid muscles.

What does the anterior jugular vein drain into?

The anterior jugular vein arises near the hyoid bone, passes downwards along the midline of the neck. Further, near the attachment of the sternocleidomastoid muscle the anterior jugular vein penetrates the cervical fascia and drains into the subclavian vein. laryngeal veins, small thyroid vein (sometimes).

Where does the superficial temporal vein drain?

The superficial temporal vein descends along the auricular anterior surface, then it joins with the maxillary vein at the level of mandibular neck and further continues as the retromandibular vein which drains into the internal or external jugular vein.

How many veins are in the face?

9 Veins of the face: 1 = superficial temporal v.; 2 = supraorbital v.; 3 = supratrochlear v.; 4 = angular v.; 5 = superior ophthalmic v.; 6 = inferior oph thalmic v.; 7 = external nasal v.; 8 = infraorbital v.; 9 = superior labial v.; 10 = inferior labial v.; 11 = facial v.; 12 = cavernous sinus; 13 = pterygoid plexus;

Where does the external jugular vein drain?

subclavian vein

Where does internal jugular vein drain?

During its descent down the neck, the internal jugular vein receives blood from the facial, lingual, occipital, superior and middle thyroid veins. These veins drain blood from the anterior face, trachea, thyroid, oesophagus, larynx, and muscles of the neck.

Are there arteries in your face?

Facial artery. Also known as the external maxillary, the facial artery branches off the external carotid artery, and it serves the components of the face. It ends underneath the eye, but there it is called the angular artery. The facial artery branches into many smaller blood vessels around the face and oral cavity.

Where is the maxillary vein located?

The maxillary veins consist of the main maxillary blood vessel and its extensions. This group of veins is located in the head. It is accompanied by the maxillary artery that runs alongside the vein. They are identified as one of the major groups of deep veins in the head.

How do you remember the branches of the external carotid artery?

Mnemonics for the branches of the external carotid artery abound.

Mnemonics

S: superior thyroid artery.
A: ascending pharyngeal artery.
L: lingual artery.
F: facial artery.
O: occipital artery.
P: posterior auricular artery.
M: maxillary artery.
S: superficial temporal artery.

What are the branches of the external carotid artery?

As it ascends, the external carotid artery gives off the following branches.

Anterior branches: lingual, facial, superior thyroid arteries.
Posterior branches: occipital, posterior auricular arteries.
Medial branch: ascending pharyngeal artery.

Where does the external carotid artery enter the skull?

The external carotid artery begins at the upper border of thyroid cartilage, and curves, passing forward and upward, and then inclining backward to the space behind the neck of the mandible, where it divides into the superficial temporal and maxillary artery within the parotid gland.

What does the great saphenous vein drain?

The great saphenous vein is a large venous blood vessel running near the inside surface of the leg from the ankle to the groin. It arises from the dorsal venous arch at the top (dorsum) of the foot and drains into the femoral vein, the main deep vein for the leg.

What does the brachiocephalic vein drain?

Brachiocephalic veins. The brachiocephalic vein, also known as an innominate vein, is a vein that returns oxygen-depleted blood from the upper limbs, neck, and head to the heart through its continuation, the superior vena cava. Major veins of the thorax and abdomen.

What happens if your jugular vein is cut?

If your jugular is punctured, Ashley warns, "you can rapidly lose blood." A needle is less likely to cause problems than a knife, but blood is likely to flow out of your jugular "more rapidly than out of a vein in wrist or arm," making a puncture a serious problem.

Is a vein an organ?

Veins are blood vessels that bring blood back to the heart and drain blood from organs and limbs. Capillaries have one layer of cells (the endothelial tunic or tunica intima) where diffusion and exchange of materials takes place.
