Study Notes

Levator Ani Muscle

The levator ani muscle supports the pelvic floor and helps maintain continence.
The levator ani muscle arises from the pelvic bone, specifically the posterior surface of the pubis, the spine of the ischium, and the sacrum.

Nerve Supply

The levator ani muscle is supplied by the sacral nerve roots S3 and S4.

Pelvic Cellular Tissue

The role of pelvic cellular tissue is to provide a cushioning effect and facilitate the movement of organs within the pelvic cavity.

Pelvic Peritoneum

The pelvic peritoneum is a serous membrane that lines the pelvic cavity and covers the pelvic organs, providing a friction-reducing surface and allowing for smooth movement of organs during different activities.
