Preferred Label : subcostal artery;
Uberon definition : An artery that runs along the bottom of the lowest rib. They constitute the lowest
pair of branches derived from the thoracic aorta, and are in series with the intercostal
arteries. Each passes along the lower border of the twelfth rib behind the kidney
and in front of the Quadratus lumborum muscle, and is accompanied by the twelfth thoracic
nerve. It then pierces the posterior aponeurosis of the Transversus abdominis, and,
passing forward between this muscle and the Obliquus internus, anastomoses with the
superior epigastric, lower intercostal, and lumbar arteries. Each subcostal artery
gives off a posterior branch which has a similar distribution to the posterior ramus
of an intercostal artery. [WP,unvetted].;
