The pelvic floor is characterized by a complex morphology because different functional systems join here. From the clinical point of view it is a borderland of several disciplines. Since a clear understanding of the pelvic floor region is crucial for both male and female pelvic surgery and for fundamental mechanisms of urogenital and /or ano-rectal
dysfunction and treatment, the authors present a morphological concept that is in accordance with actual clinical concepts. The reinterpreted anatomical concept is compared to classical morphological ideas and what is most important to functional considerations.
