Final answer:
A paraumbilical hernia is located near the umbilicus in the central peritoneal cavity region, caused by a weakness in the abdominal wall muscles around the navel allowing tissue or abdominal contents to protrude.
Step-by-step explanation:
A paraumbilical hernia refers to a type of hernia that occurs near the umbilicus (navel). In the abdominal region, the peritoneal cavity can be divided into nine regions or four quadrants using imaginary lines. A paraumbilical hernia is located close to, but not exactly at, the navel in one of these regions or quadrants. Typically, it is found in the area where the vertical band of tissue that anchors all of the small intestine except for the duodenum is located, and where the larger peritoneal folds hold various abdominal organs to the dorsal surface of the body.
The umbilical region in particular is central and surrounds the umbilicus. In this region is where a paraumbilical hernia would be prominent due to the weakening of the abdominal wall muscles around the navel, allowing abdominal contents to protrude through the gap.
