What is a cefalic vein?

Cefalic vein is one of the two main superficial veins in the human arm that extends from the wrist to the shoulder. At the top of the arm near the shoulder, the cefalic vein slipped through the groove between the main muscles of the deltooid and the pectoralis. The superficial vein is one that is located near the skin surface. The depth of the cefalic veins differs from man to man. In many people, superficial veins are visible to the eye like a bluish gray line. Blood itself is actually a dark shade of red, which is almost chestnut. Since the skin licks light, it seems that the vein is bluish gray. There are valves in the vein that work as gates or locks on the channel. They resist gravity pull and ensure that blood is always in the same direction - flows back to the heart.

There are several Veins in the arms that make up a network with capillaries to release blood back into the heart. Another main surface vein, basilic vein, runs parallel to the cefalic vein. Another vein called Median Cubital veins forms a connection between the two.

veins in the arm are the most common places used for extraction of blood samples. When a turnstile is applied to the arm to slow the blood flow, the vein stretches or expands and usually becomes more visible. Cephal vein is often used in the hospital environment to introduce fluids intravenously (IV). Blood samples are usually taken from the middle cubital vein.

While blood in the veins flows back to the heart, blood in the arteries moves away from the heart. They usually intersect. In some people who have a serious kidney disease, an annexed artery is carried out between the cephalic vein and the modification of the artificial connection, which will facilitate the dialysis process.

The origin of the word "cephalic" reveals a mixed meaning. The word cephalic comes from the Arabic tribe al-Kifal , which means the external that refers to its position on the arm. In Latin, cephalicus refers to something in common with the head. When the word p wasIt was ejected to medieval Latin, it was mistakenly translated by the Latin word cephalic.
