Recto-anal junctions
These images compare the recto-anal junction (left) with the junction of the anal canal with the anus (right). For the recto-anal junction, the transition from simple columnar epithelium with goblet cells of the rectum to the stratified squamous moist epithelium of the anal canal is abrupt. The junction of the anal canal with the anus, lined by a keratinized stratified squamous epithelium, is a bit more gradual. 400x
