Preferred Label : lumbar artery;
Uberon definition : The lumbar arteries are in series with the intercostals. They are usually four in
number on either side, and arise from the back of the aorta, opposite the bodies of
the upper four lumbar vertebrC&. A fifth pair, small in size, is occasionally present:
they arise from the middle sacral artery. They run lateralward and backward on the
bodies of the lumbar vertebrC&, behind the sympathetic trunk, to the intervals between
the adjacent transverse processes, and are then continued into the abdominal wall.
The arteries of the right side pass behind the inferior vena cava, and the upper two
on each side run behind the corresponding crus of the diaphragm. The arteries of both
sides pass beneath the tendinous arches which give origin to the Psoas major, and
are then continued behind this muscle and the lumbar plexus. They now cross the Quadratus
lumborum, the upper three arteries running behind, the last usually in front of the
muscle. At the lateral border of the Quadratus lumborum they pierce the posterior
aponeurosis of the Transversus abdominis and are carried forward between this muscle
and the Obliquus internus. They anastomose with the lower intercostal, the subcostal,
the iliolumbar, the deep iliac circumflex, and the inferior epigastric arteries.;
