Carnett's sign of intercostal nerve roots, anterior cutaneous nerve entrapment, rib-tip syndrome, myofascial pain, trigger points and rectus sheath hematomas. All abdominal wall hernias may be associated with pain and Carnett's test may be useful in their evaluation. The hernias of the anterior abdominal wall include: epigastric hernias, umbilical hernias, spigelian hernias and incisional hernias. Those of the groin include: direct inguinal hernia, indirect inguinal hernia, femoral hernia and sports hernia. Those of the pelvic wall include: sciatic hernia, obturator hernia and perineal hernia. The support hernias include: vault prolapse, enterocele, cystocele, rectocele and uterine decensus. Although most hernias can be detected
Composition of the human body Not all elements which are found in the human body in trace quantities play a role in life. Some of these elements are thought to be simple bystander contaminants without function (examples: caesium, titanium), while many others are thought to be active toxics, depending on amount (cadmium, mercury, radioactives). The possible utility and toxicity of a few elements at levels normally found in the body (aluminium) is debated. Functions have been proposed for trace amounts of cadmium and lead, although these are almost certainly toxic in amounts very much larger than normally found in the body. There is evidence that
