Abstract

The pelvic floor supports the visceral organs, is crucial in maintaining continence, facilitates micturition and evacuation and in women forms part of the birth canal. This multifunctional unit is a complex of muscles, fasciae and ligaments that have numerous interconnections and connections to bony structures, organs and the fibroelastic network within fat-containing spaces. A detailed appreciation of the pelvic floor is essential to understand normal and abnormal function. The embryology of the pelvic floor is included to help explain certain anatomical features.
