The subcutaneous inguinal ring is just above the tubercle of thepubic bone; the abdominal inguinal ring is a half inch above themiddle of the inguinal ligament. The conjoined tendon is behind thesubcutaneous ring. The abdominal muscles and skin are supplied by the lower inter-costal and first lumbar nerves. The regions of the abdomen are outlined in the followingmanner: Imagine a horizontal plane passing through the abdomenat the level of the tenth costal cartilage, and another at the levelof the anterior superior spine of the ilium. These would divide.

Then imaginetwo vertical planes passing through the middle point of the inguinalligament on either side, and dividing each of these three portionsinto three regions, making nine in all. The middle region is called the umbilical, having the umbilicuson the anterior surface. Above that is the epigastric, and below itis the hypogastric. At the sides of the epigastric region are theright and left hypochondriac. At the sides of the umbilical regionare the right and left lumbar; and at the sides of the hypogastricregion are t
