The figures accompanying the letters in Fig. 22 indicatethe superficial direction of the bowel. SernofT found that the exposed or 58 TOPOGRAPHICAL ANATOMY. peripheral part of the intestines constituted only about one sixth of the en-tire length of the canal from duodenum to cecum; the average length of thesmall intestine, according to SernofT, is 537 cm. The distance from Bx toB2 and from B2 to B3, etc., by no means represents a uniform space. GroupB (Fig. 22) of the bowels lies under the left splenic flexure of the colon,and, by passing the hand down to the mesentery at this point, can be pickedup en masse. Group C, under the hepatic flexure of the colon, can bepicked up by carrying the hand down to the mesentery between the colonand small intestines; by throwing this group over to the left side, the wholeof the right renal region is exposed. Below B and above C there is a natural. Fig. 23.—Normal Position of Ileocecal Apparatus. TheAppendix is Usually not Visible Until the Cecumis Lifted Out of the Iliac Fossa.

The following variations in relation to these groups are often found: Variation 1: Group C is displaced from its position under the right hepaticflexure over into the left flank. Variation 2: Group B crosses the median line and occupies the position ofGroup C under the hepatic flexure, while Group C goes to the left. Variation 3: Group C goes down to the left, and groups B and D go acrossand ascend on the right to occupy its place.
