The pelvic floor (PF), also known as the perineum, is the sling of muscles, and sphincters (openings) of your bladder & urethra, vagina and anus. You could liken it to the shape of a hammock.
It involves a network of tendons, muscles, ligaments and connective tissue that supports the contents of your abdominal cavity and literally stops them falling out!
When you tension your PF the sphincters should close keeping you dry.
As well as supporting the weight of the abdominal contents, the pelvic floor acts to resist an increase in the pressure in your abdomen (intra-abdominal pressure). This pressure is increased by coughing, sneezing, laughing, bending over and lifting, running and jumping.
Where is it?
The ‘hammock’ is suspended between the pubic bone at the front and the coccyx at the back and has a number of attachments around the hip and pelvis. The size of the pelvic floor resembles an open hand.
