medial umbilical ligamentの例文

• 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.
