What is linea alba in abdomen?
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.
What produces linea alba?
It’s because the linea alba is formed by the interlacing aponeuroses of three vertical abdominal muscles: external oblique, internal oblique and transversus abdominis muscles.
How can you tell linea alba?
Assess the direction of the exposed fibers of the ventral abdominal fascia to help identify the location of the linea alba. If the linea alba cannot be isolated and the incision is believed to be paramedian, carefully lift the cut edge of the subcutaneous tissue on the side suspected of housing the linea alba.
Can you feel the linea alba?
Use your fingers to feel along the entire length of the linea alba for tension. It should feel like a hardening or tightening under your fingers.

What is the difference between linea alba and umbilicus?
The umbilicus is located slightly inferior to the midpoint of the linea alba, separating the latter into two halves: a wider, supraumbilical part and a thinner, infraumbilical part. The linea alba is widest around the umbilicus.
What is the Order of the abdominal assessment?
In Brief. With abdominal assessment, you inspect first, then auscultate, percuss, and palpate. This order is different from the rest of the body systems, for which you inspect, then percuss, palpate, and auscultate. The difference is based on the fact that physical handling of peritoneal contents may alter the frequency of bowel sounds.
Which tendinous structures are attached to the linea alba?
A few tendinous structures in the surrounding area have fibers which blend with the linea alba: Upward directed medial fibers from the inguinal ligament, close to its attachment. Extraperitoneal connective tissue anchors the parietal peritoneum to the linea alba.
