The head and neck are emptied of blood by the internal and external jugular veins.
What veins drain the head and neck?
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 veins are responsible for drainage?
Jugular Veins. There are three main jugular veins – external, internal and anterior. They are ultimately responsible for the venous drainage of the whole head and neck.
Which vein will drain blood from the head neck and upper limbs?
Brachiocephalic vein (Innominate vein) The brachiocephalic vein, also known as the innominate vein, is a paired vein of the superior mediastinum that drains the venous blood from the head and neck, upper limbs and the upper part of the thorax.What kind of veins are in the neck?
The jugular veins are the major veins of the neck. The internal jugular vein is a continuation of the sigmoid sinus. It courses inferiorly within the carotid sheath, collecting tributaries in the neck. It merges with the subclavian vein at the base of the neck to form the brachiocephalic vein.
What are the three major vein pairs that drain blood from the head and neck?
Veins of head and neck The main ones draining these two regions are the: Facial vein. Inferior, middle, and superior thyroid veins. Vertebral veins.
What are the veins in your head called?
The superficial veins of the scalp, starting anteriorly and moving posteriorly, are the supratrochlear and supraorbital veins, respectively, the superficial temporal veins and its branches, the posterior auricular vein, and the occipital vein and its branches.
What is the major vein of the arm shoulder and neck?
This happens via veins. The major veins of the shoulder are: Axillary vein: This vein drains into the larger subclavian vein on its way to the heart. It is joined by the cephalic vein and the basilic vein.Which veins drain blood from the cranial and orbital cavities?
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.
What are superficial veins?A superficial vein is close to your body’s surface and is often visible to the eye. Superficial veins may appear when lifting heavy weights or during a period of intense strength training. The superficial vessels are responsible for carrying the blood from the tissues closer to the skin’s surface to the deep veins.

Is the great saphenous vein superficial?
Location. The course of the great saphenous vein takes it from the foot to the thigh. It’s a superficial vein, meaning it runs closer to the surface of the skin.
What are the superficial veins of the neck?
The anterior jugular vein is usually formed by the submandibular veins, travels downward anterior to the sternocleidomastoid muscle (SCM), and drains either into the EJV or the subclavian vein. Other superficial veins of the neck to consider are the superior, middle, and inferior thyroid veins.
What two veins drain into subclavian vein?
The main tributaries of the subclavian vein include the: External jugular vein. Dorsal scapular vein. Anterior jugular veins.
What veins and arteries supply the head?
- common carotid artery. carotid body. carotid bifurcation.
- internal carotid artery (segments) caroticotympanic artery. …
- external carotid artery (mnemonic) superior thyroid artery. …
- subclavian artery. internal thoracic.

What happens if a vein pops in your head?
If a blood vessel in the brain leaks or bursts and causes bleeding, a hemorrhagic stroke occurs. Compression from excessive bleeding may be so severe that oxygen rich blood is unable to flow to the brain tissue. A lack of oxygen in the brain can lead to swelling, or cerebral edema.
How many veins are in the neck?
The internal jugular vein is a major blood vessel that drains blood from important body organs and parts, such as the brain, face, and neck. Anatomically, there are two of these veins that lie along each side of the neck.
What two veins merge to form the superior vena cava?
On each side, the subclavian vein, the principal vein of the upper extremity, joins with the internal jugular, the principal vein of the head and neck, here, behind the medial end of the clavicle, forming the brachiocephalic vein. The two brachiocephalic veins enter the thorax and unite, forming the superior vena cava.
What is the major artery that supplies blood to the head and neck?
There are two carotid arteries in the neck — one on either side. They supply essential blood and oxygen to the brain and head. Carotid artery disease is a common but serious condition affecting the carotid arteries. Plaque buildup can cause carotid artery blockages that reduce or prevent blood flow to the brain.
Do veins in the head and neck have valves?
The anatomical literature states that veins in the head and neck lack valves, allowing bidirectional blood flow. As a result, there is potential significant flexibility in the selection of recipient veins for the microvascular anastomosis during free flap reconstruction.
Which of the following blood vessels drains the head the neck and the arms?
Jugular vein drains from the head, face, and neck.
Where does the occipital vein drain?
It originates from a plexus around the external occipital protuberance and superior nuchal line to the back part of the vertex of the skull. It usually drains into the internal jugular vein, but may also drain into the posterior auricular vein (which joins the external jugular vein). It drains part of the scalp.
What are superficial veins of the arm?
Superficial veins in the arms/upper extremities include: Digital, metacarpal, cephalic, basilic, and median veins.
What are the superficial veins of the upper limb?
There are two prominent superficial veins of the upper limb; they are the cephalic and basilic veins, and these two extensive veins originate from the venous networks of the dorsum of the hand. The hand is drained by superficial and deep veins.
Where are superficial veins located?
Superficial veins are located near the surface of the skin and have very little muscle support. The great saphenous vein is a superficial vein.
What are two differences between deep veins and superficial veins?
Superficial veins are often visible under the skin and are typically thin and wispy. They carry blood from surrounding tissues to the deep veins. Deep veins are thicker than superficial veins and buried throughout the most inner parts of the body below the skin.
What connects deep veins to superficial veins?
Short veins, called connecting veins, link the superficial and deep veins.
What is the difference between deep and superficial?
In anatomy, superficial is a directional term that indicates one structure is located more externally than another, or closer to the surface of the body. The opposite of superficial is deep. … This means it is not limited to structures on the very outside of the body, such as the skin or eyes.
What vein drains the superficial palmar arch?

Where is superficial epigastric vein?
The superficial epigastric vein runs upward and medially and drains the skin up to the umbilicus. The superficial external pudendal veins run medially then pass in front of the spermatic cord and drain the skin of the external genitalia and the adjoining part of the lower abdominal wall.
