Muscles of the pelvic floor and perineum

Learning objectives:

After finishing this study unit, you will be able to:

  1. Identify and name the muscles of the pelvic floor and perineum.
  2. Describe the attachments and innervation patterns for these muscles.
  3. Understand the anatomical relationships between the muscles of the pelvic floor.

Watch videos

The pelvic floor is formed by the bowl- or funnel-shaped pelvic diaphragm, consisting of the levator ani and coccygeus muscles and their investing fascia. Structurally, the pelvic floor separates the pelvic cavity from the perineum. Functionally, these pelvic floor muscles support the pelvic organs, keeping them in place and preventing prolapse upon straining. It also aids in maintaining both urinary and fecal continence until one can conveniently void.

Discover all about these muscles of the pelvic floor by watching this video! What’s more, this tutorial provides a comprehensive view of the pelvis itself and the associated muscles of the pelvic wall and perineum.

Take a quiz

Phew! Now that you have watched the video on the pelvic floor muscles, are you ready to consolidate your knowledge with this quiz below?

If you want to test your broader understanding, customize your own quiz and tackle questions on wider topics such as the blood supply and innervation of the pelvis.
