The umbilical region is one of the nine regions of the abdomen. It is the region that surrounds the area around the umbilicus and is placed approximately halfway between the xiphoid process and the pubic symphysis .
The medial umbilical fold is an elevation of the peritoneum (on either side of the body) lining the inner surface of the lower anterior abdominal wall formed by the underlying medial umbilical ligament (the obliterated distal portion of the umbilical artery) which the peritoneum covers. [1]

The transumbilical plane or umbilical plane, one of the transverse planes in human anatomy, is a horizontal line that passes through the abdomen at the level of the navel (or umbilicus). In physical examination, clinicians use the transumbilical plane and its intersection with the median plane to divide the abdomen into four quadrants.
The linea alba (Latin for: white line) is a strong fibrous midline structure [1] of the anterior abdominal wall [2] situated between the two recti abdominis muscles (one on either side). The umbilicus (navel) is a defect in the linea alba through which foetal umbilical vessels pass before birth. [ 1 ]
The navel (specifically abdominal wall) would be considered an umbilical hernia if the protrusion were 5 centimeters or more. The diameter of an umbilical hernia is usually 1/2-inch or more. [9] While the shape of the human navel may be affected by long term changes to diet and exercise, unexpected change in shape may be the result of ascites. [10]
Superiorly, the lateral umbilical fold ends where the vessels reach and enter the rectus sheath [1] at the arcuate line of rectus sheath; in spite of the name, the lateral umbilical folds do not extend as far superiorly as the umbilicus. [2] Inferiorly, it extends to just medial to the deep inguinal ring. [citation needed]
