Muscles of the pelvic floor and perineum

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.
