Transversalis fascia
Transversalis Fascia[edit]
The transversalis fascia is a thin aponeurotic membrane that lies between the inner surface of the transversus abdominis muscle and the extraperitoneal fat. It is an important structure in the abdominal wall, providing support and separation between the muscular and peritoneal layers.
Structure[edit]
The transversalis fascia is continuous with the fascia covering the diaphragm and the iliac fascia. It is also connected to the inguinal ligament and extends into the pelvis, where it becomes the pelvic fascia. The fascia is thin and fibrous, providing a layer of support and protection for the abdominal cavity.
Function[edit]
The primary function of the transversalis fascia is to act as a supportive layer for the abdominal wall. It helps maintain the integrity of the abdominal cavity and provides a surface for the attachment of the peritoneum. Additionally, it plays a role in the formation of the inguinal canal, which is important for the passage of structures such as the spermatic cord in males and the round ligament of the uterus in females.
Clinical Significance[edit]
The transversalis fascia is involved in various surgical procedures, particularly those related to hernia repair. Understanding its anatomy is crucial for surgeons performing laparoscopic surgery and other interventions in the abdominal region. Weaknesses in the transversalis fascia can lead to the development of inguinal hernias.

The transversalis fascia is closely associated with several other structures in the abdominal wall, including:
