The ascending lumbar vein is a vein that runs up through the lumbar region on the side of the vertebral column.
The ascending lumbar vein is a paired structure (i.e. one each for the right and left sides of the body). It starts at the common iliac veins. [1] It runs superiorly, intersecting with the lumbar veins as it crosses them. [1] It passes behind the psoas major muscle, but in front of the lumbar vertebrae. [1]
When the ascending lumbar vein crosses the subcostal vein, it becomes one of the following:
Contrast medium may be injected into the ascending lumbar vein via the femoral vein in order to visualise the spinal canal. [3]
The ascending lumbar vein may be punctured during catheterisation. [4] This can cause bleeding into the dural space. [4]
The inferior vena cava is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart. It is formed by the joining of the right and the left common iliac veins, usually at the level of the fifth lumbar vertebra.
The azygos vein is a vein running up the right side of the thoracic vertebral column draining itself towards the superior vena cava. It connects the systems of superior vena cava and inferior vena cava and can provide an alternative path for blood to the right atrium when either of the venae cavae is blocked.
The renal arteries are paired arteries that supply the kidneys with blood. Each is directed across the crus of the diaphragm, so as to form nearly a right angle.
The celiacartery, also known as the celiac trunk or truncus coeliacus, is the first major branch of the abdominal aorta. It is about 1.25 cm in length. Branching from the aorta at thoracic vertebra 12 (T12) in humans, it is one of three anterior/ midline branches of the abdominal aorta.
The internal obturator muscle or obturator internus muscle originates on the medial surface of the obturator membrane, the ischium near the membrane, and the rim of the pubis.
The small saphenous vein is a relatively large superficial vein of the posterior leg.
In human anatomy, the internal thoracic vein is the vein that drains the chest wall and breasts.
The femoral nerve is a nerve in the thigh that supplies skin on the upper thigh and inner leg, and the muscles that extend the knee. It is the largest branch of the lumbar plexus.
The lingual artery arises from the external carotid artery between the superior thyroid artery and facial artery. It can be located easily in the tongue.
The hemiazygos vein is a vein running superiorly in the lower thoracic region, just to the left side of the vertebral column.
The small cardiac vein, also known as the right coronary vein, is a coronary vein that drains parts of the right atrium and right ventricle of the heart. Despite its size, it is one of the major drainage vessels for the heart.
The pericardial sinuses are impressions in the pericardial sac formed between the points where great vessels enter it.
In anatomy, a persistent left superior vena cava is the most common variation of the thoracic venous system. It is present in between 0.3% and 0.5% of the population, and is an embryologic remnant that results from a failure to involute.
The duodenojejunal flexure or duodenojejunal junction, also known as the angle of Treitz, is the border between the duodenum and the jejunum.
The vitelline veins are veins that drain blood from the yolk sac and the gut tube during gestation.
The subcostal nerve is a mixed motor and sensory nerve contributing to the lumbar plexus. It runs along the lower border of the twelfth rib, often gives a communicating branch to the first lumbar nerve, and passes under the lateral lumbocostal arch.
The testicular vein, the male gonadal vein, carries deoxygenated blood from its corresponding testis to the inferior vena cava or one of its tributaries. It is the male equivalent of the ovarian vein, and is the venous counterpart of the testicular artery.
The lumbar veins are four pairs of veins running along the inside of the posterior abdominal wall, and drain venous blood from parts of the abdominal wall. Each lumbar vein accompanies a single lumbar artery. The lower two pairs of lumbar veins all drain directly into the inferior vena cava, whereas the fate of the upper two pairs is more variable.
A muscle fascicle is a bundle of skeletal muscle fibers surrounded by perimysium, a type of connective tissue.
The left gastric vein is a vein that derives from tributaries draining the lesser curvature of the stomach.
