The ABDOMINAL CAVITY is bounded above by the ver- tebral column and muscles, la- terally by the abdominal muscles, in front by the diaphragm, and behind by the muscular and mem- branous partition, which closes posteriorly the cavity of the pelvis. On the middle of the outer wall of the abdomen there is iu front a slight irregularity of sur- face, which is the "navel" or umbilicus. When the abdomen is opened by a median antero - posterior section through its ventral wall, and by the reflection of the walls bordering the cut, the fol- lowing organs come into view. Immediately behind the dia- phragm on the right side is seen the liver (/), with the gall-bladder protruding from amongst it (gb). In the middle line, partly beneath the liver, is the stomach (-s-), to the extreme right of which is the si)lccn (sp). From the stomach a flap of membrane, loaded with more or less fat, and called the great omentum (o), extends towards the pelvis, like an apron, and conceals the more deeply situated viscera. AVhen this is turned up or removed, a capacious transverse sacculated viscus may be seen to proceed trans- versely behind (below) the stomach; this is the great intestine, behind.
