medial umbilical ligament การใช้

Part of each umbilical artery closes up ( degenerating into what are known as the medial umbilical ligaments ), while the remaining sections are retained as part of the circulatory system.
At birth, when the placental circulation ceases, the pelvic portion only of the umbilical artery remains patent gives rise to the superior vesical artery ( or arteries ) of the adult; the remainder of the vessel is converted into a solid fibrous cord, the medial umbilical ligament ( otherwise known as the obliterated hypogastric artery ) which extends from the pelvis to the umbilicus.
