The depth of theulcer is dependent uponthe extent of the necrosis:it may involve only a partof the mucosa, but more commonly the entire thickness of the epitheliallayer is destroyed, and the submucosa or muscularis is exposed. Theedge of the ulcer is irregular, swollen, and, it may be, undermined;the base, after the slough has completely disappeared, is clean and. Fig. 355.—Small Intestine.
