Study Notes
Anterolateral Abdominal Wall
- The primary function of the anterolateral abdominal wall is to support and protect the abdominal viscera.
- The muscles that are NOT part of the anterolateral abdominal wall are the latissimus dorsi and psoas major.
- The transversalis fascia is the layer of fascia that separates the muscles of the anterolateral abdominal wall.
Innervation
- The anterolateral abdominal wall is innervated by the thoracoabdominal nerves (T7-T11), iliohypogastric nerve (L1), and ilioinguinal nerve (L1).
Rectus Abdominis Muscle
- The main function of the rectus abdominis muscle in the anterolateral abdominal wall is to flex the lumbar spine and pelvis, and to assist in forced expiration.
