Dissection of anterolateral abdominal wall
Superficial vessels and nerves; Scarpa's fascia; external oblique muscles and fascia
The left half of the specimen has been dissected to demonstrate the investing fascia (11) of the external oblique muscle and Scarpa's fascia (14). The latter is identifiable as a distinct layer of deep within the tela subcutanea in the lower part of the abdominal wall. On the right side of the specimen the fascia of the external oblique has been removed. Cutaneous nerves and vessels have been preserved bilaterally.
