| ascending lumbar vein | <anatomy, vein> Paired, vertical vein of the posterior abdominal wall, adjacent and parallel to the vertebral column, posterior to the origin of the psoas major muscle; it connects the common iliac, iliolumbar, and lumbar veins in the paravertebral line, the right vein joining the right subcostal vein to form the azygos vein, the left vein uniting with the left subcostal vein to form the hemiazygos vein. Synonym: vena lumbalis ascendens. (05 Mar 2000) |
| axillary vein | <anatomy, vein> The venous trunk of the upper limb; a continuation of the basilar and brachial veins running from the lower border of the teres major muscle to the outer border of the first rib where it becomes the subclavian vein. (12 Dec 1998) |
| azygos vein | <anatomy, vein> A vein which arises from the right ascending lumbar vein or the vena cava, enters the thorax through the aortic orifice in the diaphragm, and terminates in the superior vena cava. (12 Dec 1998) |
| azygos vein principle | A principle based on the observation that animals can survive prolonged vena caval occlusion without sequelae: if blood from the azygos vein alone is permitted to enter the heart, patients are perfused during cardiac and pulmonary bypass at flows much less than the normal resting cardiac output. Synonym: low flow principle. (05 Mar 2000) |
| basilic vein | <anatomy, vein> Arises from the ulnar side of the dorsal venous network of the hand; it curves around the medial side of the forearm, communicates with the cephalic vein via the median cubital vein, and passes up the medial side of the arm to join the axillary vein.
