Anatomy, Abdomen and Pelvis: Anterolateral Abdominal Wall Fascia

Excerpt

The anterolateral abdominal is the structure encasing the abdominal organs. This muscular layer of tissues extends from the thoracic and lumbar spine to the anterior abdominal cavity. Because the boundary between the lateral and anterior walls is not defined, the term anterolateral describes the wall as it wraps from posterior to anterior. It serves to protect the internal organs of the digestive system as well as the alimentary tract. Multiple fascia, muscle, nerves, and vasculature layers make up the anterolateral wall. The anterolateral wall demonstrates a vast degree of function and compliance with the gastrointestinal tract's needs. Throughout this topic, we explore the anatomy of the anterolateral abdominal wall, its function, and its embryologic origins.
