It is a remnant of part of biceps femoris muscle. The sacrotuberous ligament is attached by its broad base to the posterior superior iliac spine, the posterior sacroiliac ligaments (with which it is partly blended), to the lower transverse sacral tubercles and the lateral margins of the lower sacrum and upper coccyx.
The coccygeus muscle is posterior to levator ani and anterior to the sacrospinous ligament in the pelvic floor.It is a triangular plane of muscular and tendinous fibers. It arises by its apex from the spine of the ischium and sacrospinous ligament.

Female pelvic muscles Male pelvic muscles. The pelvic floor or pelvic diaphragm is an anatomical location in the human body, [1] which has an important role in urinary and anal continence, sexual function and support of the pelvic organs. [2] The pelvic floor includes muscles, both skeletal and smooth, ligaments and fascia.
This tissue provides additional support to the pelvic floor. The endopelvic fascia is one continuous sheet of tissue and varies in thickness. It permits some shifting of the pelvic structures. The fascia contains elastic collagen fibers in a 'mesh-like' structure. The fascia also contains fibroblasts, smooth muscle, and vascular vessels.
The urogenital triangle is the area bound by a triangle with one vertex at the pubic symphysis and the two other vertices at the iliac tuberosities of the pelvic bone. Components [ edit ]
Type 2 is the most common form of pelvic instability. Treatment is based on learning how to use the muscles around the pelvis more efficiently. Pelvic type 3:The ligaments do not support the joint sufficiently. This is a serious situation whereby the muscles around the joint are unable to compensate for ligament weakness.
Pelvic fascia extends to cover the organs within the pelvis. It is attached to the fascia that runs along the pelvic floor along the tendinous arch. The fascia which covers pelvic organs can be divided according to the organs that are covered: The front is known as the "vesical layer". It forms the anterior and lateral ligaments of the bladder.
