Watch this video (http://openstaxcollege.org/l/reflextest) to see how to test reflexes in the abdomen.Testing reflexes of the trunk is not commonly performedin the neurological exam, but if findings suggest a problemwith the thoracic segments of the spinal cord, a series ofsuperficial reflexes of the abdomen can localize functionto those segments. If contraction is not observed when theskin lateral to the umbilicus (belly button) is stimulated,what level of the spinal cord may be damaged?
