The area between the anterior wall of the rectus sheath and the skin comprises the fatty layers of the abdomen and contain Camper's and Scarpa's fascias that are important landmarks to the surgeon during abdominal surgery. These are not well demarcated on our cadaver but will be important during your surgical rotations. Camper's fascia is a fatty layer that is filled with small vessels that must be clamped and tied or cauterized during surgery. Scarpa's fascia is a membranous layer that marks the entry into the abdominal cavity. |
