The ligamentum teres uteri, also known as the round ligament of the uterus, is a structure found in the female reproductive system. It is a fibrous band that connects the uterus to the labia majora, which are the external genitalia. The ligamentum teres uteri is located within the broad ligament, a fold of peritoneal membrane that suspends and supports the uterus in the pelvic cavity.
The ligamentum teres uteri is present on both sides of the uterus, and it is responsible for providing support and stability to the organ. It arises from the superior aspect of the uterus, near the fallopian tubes, and travels through the inguinal canal, reaching the labia majora. This ligament plays a role in maintaining the optimal position and alignment of the uterus within the pelvic cavity, preventing excessive movement or displacement.
Moreover, the ligamentum teres uteri contains small blood vessels, nerves, and smooth muscle fibers. These components contribute to its function in maintaining the blood supply to the uterus and transmitting nerve impulses.
During pregnancy, the ligamentum teres uteri undergoes significant changes to accommodate the growing uterus. It stretches and lengthens, enabling the uterus to expand and accommodate the developing fetus. This ligament's role in pregnancy is crucial, as it provides the necessary support to the uterus and helps in maintaining its position throughout pregnancy.
Overall, the ligamentum teres uteri is an essential anatomical structure in the female reproductive system, responsible for maintaining the position, stability, and blood supply of the uterus.
