What separates right and left liver?
Anatomically, the liver is divided into a larger right lobe and a smaller left lobe by the falciform ligament (see the image below). This division, however, is of no use surgically.
What is 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 is the ligamentum teres called after birth?
Soon after birth, this vein usually obliterates and persists as the round ligament (ligamentum teres) of the liver….Umbilical vein.

Where is the ligament of Treitz?
The ligament of Treitz is a thin, triangular, double fold of the peritoneum that lies posterior to the pancreas and anterior to the left renal vein.
What separates caudate and quadrate lobes?
The right lobe is separated from the other lobes by the gallbladder fossa and the fossa for the inferior vena cava on the visceral surface of the liver. The left lobe includes the caudate and quadrate lobes. The caudate lobe lies between the fissure for the ligamentum venosum and the fossa for the inferior vena cava.
What divides the liver into medial and lateral segments?
A line drawn from the middle of the gallbladder fossa to the IVC (green) roughly divides the liver into left and right lobes. The falciform ligament (red) roughly divides the left lobe into lateral and medial segments (the left hepatic vein usually is located slightly to the left of the falciform ligament.
Why does the ductus venosus close after birth?
Shortly after birth, blood flow and blood pressure in the umbilical sinus decrease abruptly. This causes the orifice of the ductus venosus to retract and narrow, resulting in functional closure of the vascular shunt.
Which closes first foramen ovale and ductus arteriosus?
Circulatory Changes at Birth The sudden drop in right atrial pressure pushes the septum primum against the septum secundum, closing the foramen ovale. The ductus arteriosus begins to close almost immediately, and may be kept open by the administration of prostaglandins.
What is treitz muscle?
The muscle of Treitz is a smooth muscle tissue that is constituted from connective tissue and muscle fibers; it runs in continuity with the muscles of the duodenum there is no border or transition zone visible.
Why is ligament of Treitz important?
The ligament of Treitz: Contracts to help the contents of the intestines move along. Helps anchor the duodenum (first part of the small intestine, just after the stomach). Is an important landmark in human anatomy, especially for surgeons.
What is the ligamentum teres?
What is the Ligamentum Teres? The ligamentum teres (LT) or ligamentum capitis femoris is a flat pyramidal shaped ligament located intra-articularly in the hip connecting the transverse acetabular ligament to the fovea capitis of the femoral head.
What happens if you tear the ligamentum teres?
A ligamentum teres tear or rupture can lead to severe pain. This ligament connects the ball of the hip joint (femoral head) to the hip socket (acetabulum). Injuries to the ligamentum teres include complete tears, partial tears, and degenerative fraying.
Are ligamentum teres fissures normal in professional ballet dancers?
There are two normal fissures: fissure for the ligamentum teres and fissure for ligamentum venosum. The objectives of this study were to compare the frequency of atraumatic ligamentum teres (LT) tear in professional ballet dancers with that of other athletes, and to determine the relationship with clinical and imaging findings.
Can ligamentum teres improve stability in children’s hip surgery?
