A system of human anatomy, general and special . s extremity is a small dilatation which was called by Willis theantrum of the pylorus. The two curvatures give attachment to theperitoneum; the upper curve to the lesser omentum, and the lower tothe greater omentum. The anterior surface looks upwrards and for-*wards, and is in relation with the diaphragm, which separates it fromthe viscera of the thorax and from the six lower ribs, with the leftlobe of the liver, and in the epigastric region, with the abdominalparietes. The posterior surface looks downwards and backwards,and is in relation with the diaphragm, the pancreas, the third portionof the duodenum, the transverse meso-colon, the left kidney, and leftsupra-renal capsule; this surface forms the anterior boundary of thatcul-de-sac of the peritoneum which is situated behind the lesseromentum, and extends into the greater omentum. SMALL INTESTINES. The small intestine is about twenty-five feet in length, and is divi-sible into three portions, duodenum, jejunum, and ileum. Fig. 207*. The Duodenum (called SuSexaSaxrvXov by Herophilus) is somewhatlarger than the rest of the small intestines, and has received its namefrom being about equal in length to the breadth of twelve at the pylorus, it ascends obliquely backwards to theunder surface of the liver; it next descends perpendicularly in front * A vertical and longitudinal section of the stomach and duodenum, made in such adirection as to include the two orifices of the stomach. 1. The oesophagus ; upon its in-ternal surface the plicated arrangement of the cuticular epithelium is shown. 2. Thecardiac orifice of the stomach, around which the fringed border of the cuticular epithe-lium is seen. 3. The great end of the stomach. 4. Its lesser or pyloric end. 5. Thelesser curve. 6. The greater curve. 7. The dilatation at the lesser end of the stomach,which has received from Willis the name of antrum of the pylorus. This may be regardedas the rudiment of
