lateral sacral artery การใช้

On the last lumbar vertebra it anastomoses with the lumbar branch of the iliolumbar artery; in front of the sacrum it anastomoses with the lateral sacral arteries, sending offshoots into the anterior sacral foramina.
These branches are derived from the vertebral artery, the ascending cervical artery, a branch of the inferior thyroid artery in the neck, the intercostal arteries in the thorax, and from the lumbar artery, iliolumbar artery and lateral sacral arteries in the abdomen and pelvis.
