Abstract

The normal gross and microscopic morphology of the anal canal is described, including the more common variants. Constant problems in the literature are the confusing terminology and the relation of the histological zones to the so-called cloacal membrane. For this reason, the review includes remarks on the history, embryology, and nomenclature.
