- The pelvic floor is composed of multiple layers of muscles and fascia, closing the pelvic outlet, supporting and keeping the pelvic organs in a normal position. The front of the pelvic floor is the pubic symphysis and the pubic arch, the rear is the tip of the coccyx, and the two sides are the descending pubic branch, ascending branch of ischium and ischial tuberosity. The connection of the anterior border of the ischial tuberosity on both sides divides the pelvic floor into two triangles: the anterior triangle is the urogenital triangle, which passes through the urethra and vagina; the posterior triangle is the anal triangle, which passes through the anal canal. The pelvic floor is divided into the following three layers from the outside to the inside:
1. The outer layer is composed of the superficial perineal fascia and muscles, including the superficial perineal transverse muscle, bulbocavernosus muscle, ischiocavernosus muscle and external anal sphincter. All meet at the vagina and the anus, forming the perineal central tendon.
- 2. The middle layer is the urogenital ridge, covering the triangular plane in front of the pelvic exit formed between the pubic arch and the two ischial tuberosities. Including deep perineal muscles and urethral sphincter.
3. The inner layer is called the pelvic diaphragm, which is composed of the levator ani muscle and the pelvic fascia, and is penetrated by the urethra, vagina and rectum.
