The linea alba is the boundary between the upper and lower layers of your skin. It runs from near your collarbone to just above where you begin to form breasts, connecting all over the body in a continuous network with no apparent end points.

The linea alba (white line) is a single midline fibrous line created by the median fusion of the layers of the rectus sheath medial to the bilateral rectus abdominis muscles in the anterior abdominal wall. It connects to the sternum’s xiphoid process and the pubic symphysis.
So, where does the rectus abdominis come from and where does it go?
Origin and placement The rectus abdominis muscle is made up of two muscles that are vertically orientated. The medial head arises from the pubic symphysis and interlaces with the muscle fibers on the other side. It attaches to the sternum’s xiphoid process and the costal cartilages of ribs 5-7.
Similarly, how is linea alba formed? The name refers to a white line, and the linea alba is made up mostly of collagen connective tissue. It divides the left and right rectus abdominis muscles and is created by the union of the aponeuroses of the anterior abdominal wall muscles.
What is the function of the linea alba in this context?
The linea alba’s purpose is to keep the abdominal muscles in close contact to one another. The linea alba expands when there is a long-term rise in intra-abdominal pressure.
Is it true that everyone has a linea alba?
It’s known as the linea alba, and it’s evident in certain people. It goes from the xiphoid process to the pubic symphysis (just below the rib cage’s midline). The section below the umbilicus is usually the most noticeable, however it may extend all the way up to the xiphoid in certain persons.
