The base of the triangle is directed upward, and is represented by a line connecting the two epicondyles of the humerus; the sides are formed by the medial edge of the Brachioradialis and the lateral margin of the Pronator teres; the floor is formed by the Brachialis and Supinator.
The tendon of the Biceps brachii lies to the lateral side of the artery; the radial nerve is situated upon the Supinator, and concealed by the Brachioradialis.
—After the application of a ligature to the brachial artery in the upper third of the arm, the circulation is carried on by branches from the humeral circumflex and subscapular arteries anastomosing with ascending branches from the profunda brachii.

  Artery - MSN Encarta
Artery, one of the tubular vessels that conveys blood from the heart to the tissues of the body.
The arteries expand and then constrict with each beat of the heart, a rhythmic movement that may be felt as the pulse.
The most common arterial disease, and the one which is most often a contributory cause of death, particularly in old people, is arteriosclerosis, known popularly as hardening of the arteries.

  Artery - Wikipedia, the free encyclopedia
Arteries are muscular blood vessels that carry blood away from the heart.
Arterial pressure varies between the peak pressure during heart contraction, called the systolic pressure, and the minimum, or diastolic pressure between contractions, when the heart rests between cycles.
To withstand and adapt to the pressures within, arteries are surrounded by varying thicknesses of smooth muscle which have extensive elastic and inelastic connective tissues.

 Brachial artery - Wikipedia, the free encyclopedia
The brachial artery is the major blood vessel of the upper arm.
It is a continuation of the axillary artery and it originates from the lower margin of teres major muscle and continues down the arm, until it reaches the cubital fossa at the elbow.
The pulse of the brachial artery is palpable on the anterior aspect of the elbow and, with the use of a stethoscope and sphygmomanometer (blood pressure cuff) often used to measure the blood pressure.

 VI. The Arteries. 4b. 3. The Radial Artery. Gray, Henry. 1918. Anatomy of the Human Body.
The superficial branch of the radial nerve is close to the lateral side of the artery in the middle third of its course; and some filaments of the lateral antibrachial cutaneous nerve run along the lower part of the artery as it winds around the wrist.
The volar carpal branch (ramus carpeus volaris; anterior radial carpal artery) is a small vessel which arises near the lower border of the Pronator quadratus, and, running across the front of the carpus, anastomoses with the volar carpal branch of the ulnar artery.
The arteria volaris indicis radialis (radialis indicis artery) arises close to the preceding, descends between the first Interosseus dorsalis and Adductor pollicis transversus, and runs along the radial side of the index finger to its extremity, where it anastomoses with the proper digital artery, supplying the ulnar side of the finger.

 artery, carotid artery, carotid artery stenosis, carotid artery endarterectomy, abdominal aortic aneurysm, lower ...
The disease process that causes the buildup of fat and other material on the artery walls is called atherosclerosis, popularly known as "hardening of the arteries." The fatty deposit is called plaque, the narrowing of the artery is called stenosis.
The level of arterial occlusion and the location of intermittent claudication are closely correlated; eg, aortoiliac disease frequently causes claudication in the buttocks, hips and calves, and the femoral pulses are absent; in males, impotence is common and depends on the location and extent of occlusion.
Acute ischemia is caused by sudden arterial occlusion by embolization from the heart, a proximal arteriosclerotic plaque, or an aneurysm, or by an acute thrombosis on preexisting atherosclerotic disease.

ARTERY [artery] blood vessel that conveys blood away from the heart.
The largest arterial trunk is the aorta, branches of which divide and subdivide into ever-smaller tubes, or arterioles, until they terminate as minute capillaries, the latter connecting with the veins (see circulatory system).
Other important arteries are the subclavian and brachial arteries of the shoulder and arm, the carotid arteries that lead to the head, the coronary arteries that nourish the heart itself, and the iliac and femoral arteries of the abdomen and lower extremities.

Renal artery stenosis is a narrowing or blockage of the artery that supplies the kidney, caused by atherosclerosis, fibromuscular dysplasia of the renal artery wall, or scar formation in the artery.
Renal artery stenosis is caused when atheroembolic renal disease results in narrowing of the renal artery.
Renal artery stenosis may cause chronic renal failure if it affects both renal arteries or if the hypertension associated with this condition is prolonged or severe.

 Artery definition - Medical Dictionary definitions of popular medical terms
Artery: A vessel that carries blood high in oxygen content away from the heart to the farthest reaches of the body.
Since blood in arteries is usually full of oxygen, the hemoglobin in the red blood cells is oxygenated.
Angioplasty and Stents (Percutaneous Coronary Intervention, PCI) - Balloon angioplasty of the coronary artery and stents (percutaneous coronary intervention, PCI) is a non-surgical procedure that relieves narrowing and obstruction of the arteries to the muscle of the heart.

 MedlinePlus Medical Encyclopedia: Renal artery stenosis
Renal artery stenosis often causes hypertension (high blood pressure) with no other signs of its presence, and it is usually discovered in investigation for the cause of hypertension that is difficult to control.
Renal artery stenosis may cause chronic renal failure if it affects both renal arteries or if the high blood pressure associated with this condition is prolonged or severe.
A balloon angioplasty (a radiographic procedure during which a balloon-tipped catheter is threaded through the artery) or a stent placement across the stenosis may be an alternative to surgery to open the stenosed area.

Reduction of the glomerular perfusion pressure behind a stenosis of the renal artery induces dilatation of the afferent arteriole and constriction of the efferent arteriole.
The decreased resistance of the afferent arteriole is mediated by vasodilatory prostaglandins, the constriction of the efferent vessel by angiotensin II.

Inferior thyroid artery courses cranially to the thyroid gland where it anastomoses with the superior thyroid artery, a branch of the external carotid, and with the corresponding inferior thyroid artery on the other side of the neck.
Transverse cervical artery passes across the posterior triangle of the neck, anterior to the scalenus anterior and brachial plexus, and as it ap-proaches the anterior margin of the levator scapulae, it divides into a superficial and a deep branch.
The deep branch may be called the dorsal scapular artery whether it arises by itself from the 2nd or 3rd part of the subclavian artery or as a branch from the transverse cervical artery.

 Coronary Artery Disease
Coronary artery disease is the term commonly used to describe the buildup of fatty deposits and fibrous tissue (plaques) inside the arteries that supply blood to the heart (the coronary arteries).
Although coronary artery disease from atherosclerosis is the most common reason for arteries to become blocked, there are rarer cases in which problems in the coronary arteries result from other medical conditions.
Because the extent of coronary artery disease does not always match the severity and length of chest pain, it is important for patients with chest pain to have their symptoms evaluated promptly by a doctor.

Carotid artery disease is a form of disease that affects the vessels leading to the head and brain (cerebrovascular disease).
