Anterolateral abdominal wall 9. Layers ( from superficial to deep) • Skin • Superficial fascia (2layers below umbilicus) • Deep fascia • Anterolateral muscles(3 layers of paired m,) • Transversalis fascia • Extraperitoneal fascia • Parietal peritoneum
Anterolateral abdominal wall 1st.Skin 2nd .Superficial fascia Fatty layer(Camper's fascia)continuous with the superficial fascia over the rest of the body. Membranous layer (Scarpa's fascia) below umbilicus passes over the inguinal ligamentto fuse the deep fascia of the thigh(fascia lata). In the perineum,it is attaches on each side to the margins of the pubic arch and is know as Colles'fascia. 3rd.Investing fascia(deep fascia)
