Clinical examination of appendix

Compare the pictures on the video on the left  with those of the digital locator to locate the appendix from the skin on the right

  DIGITAL LOCATOR OF APPENDIX: Layer 1 Skin of abdomen (anterior abdominal wall). Layer 2- Layer of Camper's fascia. Layer 3 - layer of Scarpa's fascia. Layer  4 - layer of external oblique muscle/aponeurosisLayer 5- layer of rectus sheath. Layer 6- layer of internal oblique. Layer 7 - layer of transversus abdominis. Layer 8- layer of transversus abdominis/parietal peritoneum. Layer 9- layer of greater sac of peritoneum. Layer 10- layer of small intestine. Layer 11- layer of transverse colon. Layer 12- layer of posterior abdominal wall. Layer 13 - layer of deep posterior abdominal wall. Layer 14 - layer of bones of abdominal region..
