Umbilical fascia

Umbilical Fascia

The umbilical fascia is a layer of connective tissue that is part of the abdominal wall. It is located in the region of the umbilicus, commonly known as the navel. This fascia plays a crucial role in supporting the structures of the abdominal wall and maintaining the integrity of the umbilical region.

Anatomy

The umbilical fascia is situated beneath the skin and subcutaneous tissue of the abdomen. It is part of the transversalis fascia, which lines the inner surface of the abdominal wall. The umbilical fascia specifically refers to the portion of this fascia that surrounds the umbilicus.

The fascia is composed of dense connective tissue, providing strength and support to the abdominal wall. It is continuous with the surrounding fascial layers, including the rectus sheath and the peritoneum.

Function

The primary function of the umbilical fascia is to provide structural support to the umbilical region. It helps to maintain the position of the umbilicus and supports the passage of structures such as the umbilical vein and umbilical arteries during fetal development.

In adults, the umbilical fascia contributes to the overall integrity of the abdominal wall, helping to prevent herniation and other structural issues.

Clinical Significance

The umbilical fascia is clinically significant in the context of umbilical hernias. An umbilical hernia occurs when part of the intestine or other tissue protrudes through a weak spot in the abdominal wall near the umbilicus. This condition is more common in infants but can also occur in adults.

Surgical repair of an umbilical hernia often involves reinforcing the umbilical fascia to prevent recurrence. Understanding the anatomy and function of this fascia is crucial for surgeons performing such procedures.
