Anatomy, Abdomen and Pelvis: Anterolateral Abdominal Wall Fascia

Excerpt

The anterolateral abdominal is the structure encasing the abdominal organs. It is the muscular layer of tissues that extends from the thoracic and lumbar spine to the anterior abdominal cavity. The boundary between the lateral and anterior wall is not defined, and therefore, the name anterolateral is used to describe 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 layers of fascia, muscle, nerves, and vasculature make up the anterolateral wall. The anterolateral wall demonstrates a vast degree of function as well as compliance for what the gastrointestinal tract needs. Throughout this article, we will explore the anatomy of the anterolateral abdominal wall, its function, and its embryologic origins.
