what ligament is made via a double layer of peritoneum and during development was used as a vessel for the umbilical vein?
falciform ligament - anchors liver to the anterior abdominal wall and the diaphragm
pubic bone landmarks
-Pubic symphysis
-Pubic crest
-Pubic tubercle

2 structures of abdominal wall
-Umbilicus
-Superficial fascia
rectus sheath is made of what aponeurosis
- Aponeurosis of external oblique m.
- Aponeurosis of internal oblique m.
- Aponeurosis of transverse abdominal m.
what type of folds are in the umbilicus
Median umbilical fold
Medial umbilical folds
Lateral umbilical folds
what extends from the cartilage of the ninth rib to the pubic tubercle. It is formed by the aponeurosis of the internal oblique at its line of division to enclose the rectus?
linea semilunaris
what do the anterior and posterior layers of the rectus sheath blend contralaterally?
linea alba
What does arcuate line separate?
It is the demarcation where the internal oblique and transversus abdominis aponeuroses of the rectus sheath start to pass anteriorly to the rectus abdominis muscle, leaving only the transversalis fascia posteriorly
