Gallbladder

Gall bladder has no muscularis mucosae and hence its mucosa consists of only lamina propria and epithelium. Its submucosa merges with the lamina propria and its external coat is fibromuscular.

Epithelium is simple columnar.  It has mucosal folds like Fallopian tube, and not villi.

Differential diagnosis:  Gallbladder can quite easily be confused with only one other structure with mucosal fold, the Fallopian tube. But if it is the ampulla of that structure, the highly branching mucosal folds are distinct. Its isthmus, however has similar folds as gall bladder.
