The levator ani is anterior laterally (each side) from the pubic bone, the ischial spine, and the pelvic wall. This is a thickening of the obturator fascia attaches to the levator ani. It droops superiorly passing toward the midline, and inserting on these three locations which are: the anococcygeal ligament, the coccyx, and the contralateral levator ani.
The muscle essentially has four parts which are the levator prostatae, the puborectalis, the pubococcygeus, and the iliococcygeus. The coccygeus is the posterior-most muscle of the pelvic floor; it is on the same plane as and immediately posterior to the iliococcygeus. The pelvic diaphragm counters abdominal pressure, and, with the thoracic diaphragm, assists in micturition, defecation, and childbirth. It is a key structural component that assists the uterus to resist vaginal, bladder, and rectal prolapse.
The obturator internus is a lateral rotator of the hip joint. Connecting from the obturator foramen on the pelvic side, it then passes down past the obturator foramen through the lesser sciatic foramen. It inserts itself on the other side on the medial surface of the greater trochanter of the femur. As complex as this may seem, it really isn't and it's just a way of describing our bodies accurately without a 3 dimensional model.
Emeryville, CA - Ergonomics By Local Ergonomists Training With Best Evaluators
SYNOPSIS: We look at the anatomy of sitting and how posture plays into how you feel by the end of the day. Ergonomics ensures that you are comfortable and pain free everyday you work ensuring your longevity.
Various body parts can experience pain at work

Emeryville has various companies that have decided on standards for their office and possibly laboratory settings. These companies sometimes decide on them through project managers, space planners, etc. without consulting an ergonomic specialist. Without someone with knowledge about workstation features and how they fit anatomy, you may find your workers coming down with musculoskeletal illnesses. If you are interested more about anatomy or employing ergonomics in your workplace, contact a consultant with Ergobility today.
This article will cover some anatomy taking a look at the muscles of the pelvis and torso. The muscles of the pelvis form the pelvic floor in the pelvic outlet (coccygeus and the levator ani) contribute to what is called "the pelvic wall" (consisting of obturator internus and the piriformis). The pelvic wall is a portion of the bony pelvis and the both the sacrotuberous and the sacrospinous ligaments. These fascia-covered pelvic floor muscles are called the pelvic diaphragm. This structure separates the pelvic viscera from the perineal structures. As muscular diaphragms do, this one, particularly the thoracic uro-genital, is a structure that is meant to move. These structures are also incomplete as the fusion of the two coccygeus muscles is interrupted by the coccyx and anteriorly the levator ani to provide an opening, or hiatus, for the anal canal, the vagina, and the urethra.
The levator ani is anterior laterally (each side) from the pubic bone, the ischial spine, and the pelvic wall. This is a thickening of the obturator fascia attaches to the levator ani. It droops superiorly passing toward the midline, and inserting on these three locations which are: the anococcygeal ligament, the coccyx, and the contralateral levator ani.

The pelvic diaphragm counters abdominal pressure, and, with the thoracic diaphragm, assists in micturition, defecation, and childbirth.
