text: The abdomen is enclosed by a wall formed by the abdominal muscles, vertebral column and the ilial bones; it is divided into 9 regions (3 upper—right hypochondriac, epigastric, left hypochondriac; 3 middle—right lateral, umbilical, left lateral; 3 lower—right inguinal, pubic, left inguinal) by 4 imaginary lines projected onto the anterior wall, of which 2 horizontally transect the body—the upper at the level of the cartilages of the 9th ribs, the lower at the iliac crests—and 2 extend vertically on each side of the body from the cartilage of the 8th rib to the centre of the inguinal ligament.
