Lateral Branches of Abdominal Aorta 3D

  • Description                                                         
    • * Develop from the lateral splanchnic or mesonephric arteries and supply the viscera derived from the intermediate mesoderm.
    • * These are right and left inferior phrenic arteries, middle suprarenal arteries, renal arteries, and testicular or ovarian arteries.

                                                                                                                       

  • Inferior Phrenic Arteries:
    • * Arise from the aorta immediately below the aortic hiatus, supply the diaphragm, and give rise to three superior suprarenal arteries.

                                                                                                                             

  • Middle Suprarenal Arteries:
    • * Arise from the aorta and run laterally on the crura of the diaphragm just superior to the renal arteries.

                                                                                                                                              

  • Renal Arteries:
    • * Arise from the aorta inferior to the origin of the superior mesenteric artery.
    • * The right artery is longer and a little lower than the left. The left artery passes posterior to the left renal vein.
    • * Give rise to the inferior suprarenal and ureteric arteries.
    • * Divide into the superior, anterosuperior, anteroinferior, inferior, and posterior segmental branches.

                                                                                                                              

  • Testicular or Ovarian Arteries:
    • * Descend retroperitoneally and run laterally on the psoas major muscle and across the ureter.
    • * The testicular artery accompanies the ductus deferens into the scrotum, where it supplies the spermatic cord, epididymis, and testis.
    • * The ovarian artery enters the suspensory ligament of the ovary, supplies the ovary, and anastomoses with the ovarian branch of the uterine artery.
