What does the linea semilunaris represent?
The linea semilunaris is a vertical, curved structure that runs along the lateral edges of the rectus abdominis muscle in the anterior abdominal wall. It is the site of union where tendons of the lateral abdominal muscles meet the sheath surrounding the rectus abdominis muscle, also known as the rectus sheath.
Where is Linea Arcuata located?
Anatomical terms of bone The arcuate line of the ilium is a smooth rounded border on the internal surface of the ilium. It is immediately inferior to the iliac fossa and Iliacus muscle. It forms part of the border of the pelvic inlet.
What is Linea Arcuata?
Linea arcuata –> arcuate line. An arching or bow-shaped line.
What is Linea Semicircularis?
The arcuate line of the abdomen (or linea semicircularis) is a horizontal line that demarcates the lower limit of the posterior layer of the rectus sheath. It is also where the inferior epigastric vessels perforates the rectus abdominus.
What makes up the linea alba?
The linea alba (Latin for white line) is a single midline fibrous line in the anterior abdominal wall formed by the median fusion of the layers of the rectus sheath medial to the bilateral rectus abdominis muscles. It attaches to the xiphoid process of the sternum and the pubic symphysis.
Where does the linea alba start and end?
In humans, the linea alba runs from the xiphoid process to the pubic symphysis down the midline of the abdomen.
Where does the inferior epigastric artery come from?
The inferior epigastric artery arises commonly from the external iliac artery just superior to the inguinal ligament. This artery runs superiorly in the transversalis fascia to enter the rectus sheath below the arcuate line, and finally anastomoses with the superior epigastric artery [1].
Why is my linea alba so prominent?
It’s likely caused by shifts in hormones. The increase in hormones causes melanin-producing cells in the skin to produce more pigment. Because the linea alba is always present (it’s just too light to be seen), the increased pigment makes the line very obvious.
Is linea alba normal?
Do you notice a thin white line running along the pink tissue there? This a condition known as linea alba. It’s typically harmless and doesn’t require treatment. But it may be worth getting checked out.

Where is the semicircular line in the abdominal wall?
The semicircular line is defined as a posterior sheath located between the umbilicus and the pubis and has a concavity oriented toward the pubis [ 1, 3, 4 ]. Above this line, the internal oblique aponeurosis divides into a posterior lamina and a anterior lamina.
Which is inferior to the arcuate line of rectus sheath?
Inferior to the arcuate line, the aponeuroses of the external oblique muscle, the internal oblique muscle, and the transversus abdominis muscle merge and pass superficial to the rectus abdominis muscle. Therefore, inferior to the arcuate line, the rectus abdominis rests directly on the transversalis fascia .
Is the arcuate line inferior to the Spigelian line?
Spigelian hernias and, exceedingly rarely, arcuate line hernias may occur inferior to the arcuate line. The arcuate line must be incised at its lateral-most point in order to enter the space of Retzius and space of Bogros from within the rectus sheath during surgery during retrorectus repair and transversus abdominis release.
What is the arcuate line of the abdomen?
Anatomical terminology. The arcuate line of the abdomen, linea semicircularis or Douglas’ line is a horizontal line that demarcates the lower limit of the posterior layer of the rectus sheath.
