What is the origin of ligamentum teres?
ligamentum teres (anatomy) The ligamentum teres is the obliterated fibrous remnant of the left umbilical vein of the fetus. It originates at the umbilicus. It passes superiorly in the free margin of the falciform ligament.
Which ligament of liver is derived from a vessel?

What is the embryological origin of the falciform ligament?
The falciform ligament derives from the ventral mesentery, which is a part of the embryological foregut and forms a connection between the ventral abdominal wall and the liver. The umbilical vein, which is within the umbilical cord, carries oxygen-rich blood from the placenta to the fetal liver.
Why falciform ligament is called ligament?
The ligament derives its name from its shape, which is reminiscent of a sickle. Falciform is Latin for sickle-shaped.
Where is the ligamentum teres found?
In human anatomy, the ligament of the head of the femur (round ligament of the femur, ligamentum teres femoris, or the foveal ligament) is a ligament located in the hip. It is triangular in shape and somewhat flattened.
What is the ligamentum teres?
The ligamentum teres (LT) consists of two bands that originate on the ischial and pubic sides of the acetabular notch and insert on the fovea capitis of the femoral head. Recent studies have established the LT as an important hip stabilizer in a squatting position, particularly in patients with osseous instability.
What is ligamentum teres a remnant of?
The ligamentum teres is the remnant of the umbilical vein working throughout fetal life. Initially a pair of the umbilical veins entered the sinus venosus.
What is the ligamentum teres of the liver?
Ligamentum teres (or round ligament) of the liver is a cord-like ligament found within the falciform ligament on the inner surface of the anterior abdominal wall and represents a remnant of the umbilical vein, which is a connecting venous structure between the placenta and the umbilical portion of the left portal vein.
What are the embryonic origins of the ligamentum venosum and ligamentum teres hepatis?
The ligamentum venosum is the fibrous remnant of the ductus venosus of the fetal circulation. Usually, it is attached to the left branch of the portal vein within the porta hepatis (gateway to theliver). It may be continuous with the round ligament of liver (ligamentum teres hepatis).
What are fetal remnant ligaments?
Fetal remnant ligament: the remnants of a fetal tubular structure. Periodontal ligament: a group of fibers that attach the cementum of teeth to the surrounding alveolar bone.
What is the ligamentum teres a remnant of?
How did the falciform ligament get its name?
The falciform ligament divides the left and right subphrenic compartments but may still allow passage of fluid from one to the other. Blood supply is very variable, and a separate hepatic falciform artery was only seen in 67% of cadavers in one study 3,4. The ligament derives its name from its shape, which is reminiscent of a sickle.
Is there a separate hepatic artery for falciform ligament?
Blood supply and drainage is very variable, and a separate hepatic falciform artery was only seen in 67% of cadavers in one study 3,4. arterial supply left inferior phrenic artery and middle hepatic artery anastomose to form a single artery that then ramifies as 6-12 branches to supply the falciform ligament
When does the ligamentum arteriosum form after birth?
Anatomical terminology. The ligamentum arteriosum (Latin: arterial ligament) is a small ligament that is the remnant of the ductus arteriosus formed within three weeks after birth.
Where does the ligamentum attach to the aorta?
At the superior end, the ligamentum attaches to the aorta—at the final part of the aortic arch (the isthmus of aorta) or the first part of the descending aorta. On the other, inferior end, the ligamentum is attached to the top of the left pulmonary artery.
