Median Cubital Vein
In human anatomy, the median cubital vein (or median basilic vein) is a superficial vein of the arm on the anterior aspect of the elbow. It classically shunts blood from the cephalic to the basilic vein at the roof of the cubital fossa. It is typically the most prominent superficial vein in the human body, and is visible when all other veins are hidden by fat or collapsed during a shock. It arises from the cephalic vein 2.5 cm (one inch) below the lateral epicondyle of the humerus, runs obliquely upward and medially, and empties into the basilic vein 2.5 cm (one inch) above the medial epicondyle. It is routinely used for venipuncture (taking blood) and as a site for an intravenous cannula. This is due to its particularly wide lumen, and its tendency to remain stationary upon needle insertion. Structure The median cubital vein is a superficial vein of the arm. It lies on the anterior aspect of the elbow, in the cubital fossa superficial to the bicipital aponeurosis. It brid ...

Superficial Vein
Superficial veins are veins that are close to the surface of the body, as opposed to deep veins, which are far from the surface. Superficial veins are not paired with an artery, unlike the deep veins, which are typically associated with an artery of the same name. Superficial veins are important physiology, physiologically for cooling of the body. When the body is too hot, the body shunts blood from the deep veins to the superficial veins to facilitate heat transfer to the body's surroundings. Superficial veins are often visible underneath the skin. Those below the level of the heart tend to bulge out, which can be readily witnessed in the hand, where the veins bulge significantly less after the arm has been raised above the head for a short time. Veins become more visually prominent when lifting heavy weight, especially after a period of proper strength training. Physiologically, the superficial veins are not as important as the deep veins (as they carry less blood) and ar ...

Lumen (anatomy)
In biology, a lumen (: lumina) is the inside space of a tubular structure, such as an artery or intestine. It comes . It can refer to: *the interior of a vessel, such as the central space in an artery, vein or capillary through which blood flows *the interior of the gastrointestinal tract *the pathways of the bronchi in the lungs *the interior of renal tubules and urinary collecting ducts *the pathways of the female genital tract, starting with a single pathway of the vagina, splitting up in two lumina in the uterus, both of which continue through the fallopian tubes *the fluid-filled cavity forming in the blastocyst during pre-implantation development called the blastocoel In cell biology, lumen is a membrane-defined space that is found inside several organelles, cellular components, or structures, including thylakoid, endoplasmic reticulum, Golgi apparatus, lysosome, mitochondrion, and microtubule. Transluminal procedures ''Transluminal procedures'' are procedures occur ...

Vacutainer
A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper creating a vacuum seal inside of the tube, facilitating the drawing of a predetermined volume of liquid. Vacutainer tubes may contain additives designed to stabilize and preserve the specimen prior to analytical testing. Tubes are available with a safety-engineered stopper, with a variety of labeling options and draw volumes. The color of the top indicates the additives in the vial. Vacutainer tubes were invented by Joseph Kleiner in 1949. ''Vacutainer'' is a registered trademark of Becton Dickinson, which manufactures and sells the tubes today. Principles The Vacutainer needle is double-ended: the inner end is encased in a thin rubber coating that prevents blood from leaking out if the Vacutainer tubes are changed during a multi-draw, and the outer end which is inserted into the vein. When the needle is screwed into the translucent plastic needle holder, the coated end ...

Tourniquet
A tourniquet is a device that is used to apply pressure to a limb or extremity in order to create ischemia or stopping the flow of blood. It may be used in emergencies, in surgery, or in post-operative rehabilitation. A simple tourniquet can be made from a stick and a rope, but the use of makeshift tourniquets has been reduced over time due to their ineffectiveness compared to a commercial and professional tourniquet. This may stem the flow of blood, but side effects such as soft tissue damage and nerve damage may occur. History During Alexander the Great’s military campaigns in the fourth century BC, tourniquets were used to stanch the bleeding of wounded soldiers. Romans used them to control bleeding, especially during amputations. These tourniquets were narrow straps made of bronze, using only leather for comfort. In 1718, French surgeon Jean Louis Petit developed a screw device for occluding blood flow in surgical sites. Before this invention, the ''tourniquet' ...

Phlebotomy
Phlebotomy is the process of making a puncture in a vein, usually in the arm, with a cannula for the purpose of drawing blood. The procedure itself is known as a venipuncture, which is also used for intravenous therapy. A person who performs a phlebotomy is called a phlebotomist, although most doctors, nurses, and other technicians can also carry out a phlebotomy. In contrast, phlebectomy is the removal of a vein. Phlebotomies that are carried out in the treatment of some blood disorders are known as '' therapeutic phlebotomies''. The average volume of whole blood drawn in a therapeutic phlebotomy to an adult is 1 unit (450–500 ml) weekly to once every several months, as needed. Etymology From ( – 'blood vessel, vein' + 'cutting'), via (modern French ). Phlebotomies Phlebotomies are carried out by phlebotomists – people trained to draw blood mostly from veins for clinical or medical testing, transfusions, donations, or research. Blood is collected primarily by per ...

Brachial Veins
In human anatomy, the brachial veins are venae comitantes of the brachial artery in the arm proper. Because they are deep to muscle, they are considered deep veins. Their course is that of the brachial artery (in reverse): they begin where radial veins and ulnar veins join (corresponding to the bifurcation of the brachial artery). They end at the inferior border of the teres major muscle. At this point, the brachial veins join the basilic vein to form the axillary vein. The brachial veins also have small tributaries that drain the muscles of the upper arm, such as biceps brachii muscle and triceps brachii muscle.

Median Antebrachial Vein
The median antebrachial vein, also known as median vein of forearm, is a superficial vein of the (anterior) forearm. It arises from - and drains - the superficial palmar venous arch, ascending superficially along the anterior forearm before ending by opening into the median cubital vein near the junction with the basilic vein within the cubital fossa; alternately, it may fork distal to the elbow and proceed to drain into both aforementioned veins. A bifurcation of the median antebrachial vein produces the (medial) intermediate basilic vein and the (lateral) intermediate cephalic vein; the two veins produced by such a split may replace the median cubital vein In human anatomy, the median cubital vein (or median basilic vein) is a superficial vein of the arm on the anterior aspect of the elbow. It classically shunts blood from the cephalic to the basilic vein at the roof of the cubital fossa. It is ty .... References Veins of the upper limb {{circulatory-stub ...

Bicipital Aponeurosis
The bicipital aponeurosis (also known as lacertus fibrosus) is a broad aponeurosis of the biceps brachii, which is located in the cubital fossa of the elbow. It separates superficial from deep structures in much of the fossa. Structure The bicipital aponeurosis originates from the distal insertion of the biceps brachii, and inserts into the deep fascia of the forearm. The biceps tendon inserts on the radial tuberosity, and the bicipital aponeurosis lies medially to it. It reinforces the cubital fossa, helping to protect the brachial artery and the median nerve running underneath. Variations Some individuals (about 3% of the population) have a ''superficial ulnar artery'' that runs superficially to the bicipital aponeurosis instead of underneath it. These individuals are at risk for accidental injury to the ulnar artery during venipuncture. Clinical significance The bicipital aponeurosis is superficial to the brachial artery and the median nerve, but deep to the median cu ...

Cannula
A cannula (; Latin meaning 'little reed'; : cannulae or cannulas) is a tube that can be inserted into the body, often for the delivery or removal of fluid or for the gathering of samples. In simple terms, a cannula can surround the inner or outer surfaces of a trocar needle thus extending the effective needle length by at least half the length of the original needle. Its size mainly ranges from 14 to 26 Needle gauge comparison chart, gauge. Different-sized cannula have different colours as coded. Decannulation is the permanent removal of a cannula (intubation, extubation), especially of a tracheostomy cannula, once a physician determines it is no longer needed for breathing. Medicine Cannulas normally come with a trocar inside. The trocar is a needle, which punctures the body in order to get into the intended space. Intravenous cannulas are the most common in hospital use. A variety of cannulas are used to establish cardiopulmonary bypass in cardiac surgery. A nasal cannula ...

Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest.
