The transversalis fascia (or transverse fascia) is the fascial lining of the anterolateral abdominal wall [1] [2] situated between the inner surface of the transverse abdominal muscle, and the preperitoneal fascia.

The transverse abdominal muscle (TVA), also known as the transverse abdominis, transversalis muscle and transversus abdominis muscle, is a muscle layer of the anterior and lateral (front and side) abdominal wall, deep to (layered below) the internal oblique muscle.

The transversalis fascia sits between the transversus abdominis muscle and the extraperitoneal fat and peritoneum. It is continuous with the inferior surface of the diaphragm superiorly and the thoracolumbar fascia posteriorly.

2023年4月16日 · Transversalis fascia is the lining fascia of the anterolateral abdominal wall which lies between the transversus abdominis muscle and peritoneum. The transversalis fascia, inferior diaphragmatic fascia, pelvic fascia and iliacus fascia form a continuous lining of the abdominal and pelvic cavity:

2023年10月30日 · The transversus abdominis is a broad paired muscular sheet found on the lateral sides of the abdominal wall. Along with the external abdominal oblique and the internal abdominal oblique, it comprises the lateral abdominal muscles.

2023年7月24日 · Transversalis Fascia The endoabdominal fascia lines the entire abdominal cavity. It has specific names which are based on anatomic locations and include the diaphragmatic fascia, obturator fascia, iliopsoas fascia, among others.

The transversalis fascia is a thin aponeurotic membrane which lies between the inner surface of the Transversus and the extraperitoneal fat. It forms part of the general layer of fascia lining the abdominal parietes, and is directly continuous with the iliac and pelvic fasciae.

2023年8月25日 · It has two layers, a relatively firm one lining the deep surface of the deepest muscular layer of abdominal wall, called the transversalis fascia and a second layer which blends with the parietal peritoneum. The second one is more flexible than the transversalis fascia.

2025年1月16日 · The transversalis fascia is a thin layer of connective tissue that is composed of collagen fibers and elastic fibers. It is located within the abdominal wall, lying deep to the external oblique muscle and superficial to the parietal peritoneum.

According to Terminologia Anatomica, endoabdominal fascia comprises: 1) transversalis fascia and 2) investing abdominal fascia: deep, intermediate and superficial. Thus, transversalis fascia is the innermost layer of endoabdominal fascia and, consequently, not synonymous with it.
