Arc Line

Arc-shaped line: from the Latin arcus - arc, arcarius - arcuate.

Arcuate line is an arched border that can be found on various parts of the body. In anatomy, the arcuate line is the lower edge of the posterior wall of the rectus sheath, located 3–5 centimeters below the navel. Also, it can be found on the inner surface of the ilium and separates its body and wings.

In medicine, an arcuate line is used to determine the location of organs and tissues in the abdominal cavity. It can also be used to locate blood vessels and nerve bundles that pass through the area.

In addition, the arcuate line can be used in plastic surgery to create a more aesthetic appearance of the abdomen after abdominal surgery.

Thus, the arcuate line plays an important role in anatomy and medicine, and knowledge of it can help in the diagnosis and treatment of various diseases.

The arcuate line (linea archiata) is an anatomical structure, arcuate in shape, running along the lower surface of the posterior wall of the vagina of the rectus abdominis muscle from bottom to top; upon reaching the aponeurosis of the serratus anterior muscle, it passes to the anterior wall of the abdomen, crosses the anterior abdominal wall in a straight line and then goes down and passes into the tendon of the external oblique muscle of the abdomen in the form of a sharply curved section. The point marking the beginning of the line is called the inferior edge of the goblet of the rectus abdominis muscle.
