ascending lumbar vein, vena lumbalis ascendens
Paired, vertical vein of the posterior abdominal wall, adjacent and parallel to the vertebral column, posterior to the origin of the psoas major muscle (bodies of vertebrae and intervertebral disks from the twelfth thoracic to the fifth lumbar); it connects the common iliac (dorsal bone of the pelvis), 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 (below the ribs); vein to form the hemiazygos vein (merger of the left ascending lumbar vein with the left subcostal vein).

lumbar facet joint (s) (noun), lumbar facet joints
Any of the four projections that link one vertebra of the spine to an adjacent vertebra: Lumbar facet joints are increasingly held responsible for low back aches.

The lumbar facet joints are subjected to continuous stresses throughout life and by degeneration, reactive remodeling, and hypertrophy (enlargement); all of which can affect the joints.

lumbar palpation (s) (noun), lumbar palpations (pl)
The probingĀ or physical manipulation of a ptotic or enlarged kidney with one hand while the other hand is placed under the lumbar region, the subject being examined in the dorsal decubitus or reclining position: Jack was feeling quite ill and when he was examined by his physician, a lumbar palpation was used to determine the condition of his internal organs and especially of the organ that cleans blood and removes the waste.
lumbar puncture (s) (noun), lumbar punctures (pl)
A spinal tap which is a procedure in which spinal fluid is removed from the spinal canal for the purpose of diagnostic testing.

Lumbar puncture is especially helpful in the diagnosis of inflammatory diseases of the central nervous system; especially, infections, such as meningitis. Lumbar puncture can also provide clues to the diagnosis of stroke, spinal cord tumor, and cancer in the central nervous system.

A lumbar puncture is so-called because the needle goes into the lumbar portion of the back. Other names for a lumbar puncture (an LP) include spinal puncture, thecal puncture, and rachiocentesis.

A lumbar puncture can also be done for therapeutic purposes; namely, as a way of administering antibiotics, cancer drugs, or anesthetic agents into the spinal canal.

Spinal fluid is sometimes removed by lumbar puncture for the purpose of decreasing spinal fluid pressure in patients with uncommon conditions; such as, normal-pressure hydrocephalus and benign intracranial hypertension.

After a local anesthesia is injected into the small of the back (the lumbar area), a needle is inserted in between the nearby bony building blocks (vertebrae) into the spinal canal to make the lumbar puncture. The needle is usually placed between the 3rd and 4th lumbar vertebrae. Spinal fluid pressure can then be measured and cerebrospinal fluid (CSF) removed for testing.

The cerebrospinal fluid circulates around the brain and spinal cord (the central nervous system). This "water bath" acts as a support of buoyancy for the brain and spinal cord. The support of the cerebrospinal fluid helps to protect the brain from injury.

Spinal fluid obtained from the lumbar puncture can be used to diagnose many important diseases: such as, bleeding around the brain; increased pressure from hydrocephalus; inflammation of the brain, spinal cord, or the adjacent tissues (encephalitis, meningitis); tumors of brain or spinal cord, etc. Sometimes spinal fluid can indicate diseases of the immune system; such as, multiple sclerosis.

When spinal fluid is removed during a lumbar puncture, the risks include headache, brain herniation, bleeding, and infection. Each of these complications are uncommon with the exception of headache, which can appear from hours to up to a day after lumbar puncture.

Headaches occur less frequently when the patient remains lying flat one to three hours after the procedure. The benefits of the lumbar puncture depend on the exact situation but a lumbar puncture can usually provide lifesaving information.

lumbar veins, venae lumbales
Five in number, these veins accompany the lumbar arteries, drain the posterior body wall and the lumbar vertebral venous plexuses, and terminate anteriorly as follows: the first and second in the ascending lumbar vein, the third and fourth in the inferior vena cava, and the fifth in the iliolumbar vein; all communicate via the ascending lumbar veins.

right lumbar lymph nodes
The chain of lymph nodes associated with the inferior vena cava; it is divided into three groups: nodi lymphatici cavales laterales on the right of the inferior vena cava; nodi lymphatici precavales, in front of the inferior vena cava; nodi lymphatici postcavales, under nodus lymphaticus, behind the inferior vena cava.

The inferior vena cava are the large venous trunk which receives blood from the lower extremities and from the pelvic and abdominal organs. It travels through the abdomen (from the lower extremities) and returns blood to the right atrium, a thin-walled chamber of the heart which pumps blood into the right ventricle, of the heart.
