Superior fascia of diaphragm of pelvis
|Superior fascia of diaphragm of pelvis|
|Coronal section of pelvis, showing arrangement of fasciae. Viewed from behind.|
|Latin||fascia superior diaphragmatis pelvis|
|Gray's||subject #119 421|
The diaphragmatic part of the pelvic fascia covers both surfaces of the Levatores ani. The layer covering the upper surface of the pelvic diaphragm follows, above, the line of origin of the Levator ani and is therefore somewhat variable.
In front it is attached to the back of the symphysis pubis about 2 cm. above its lower border.
It is attached to this fascia along a line which pursues a somewhat irregular course to the spine of the ischium.
The irregularity of this line is because the origin of the Levator ani, which in lower forms is from the pelvic brim, is in man lower down, on the obturator fascia.
Tendinous fibers of origin of the muscle are therefore often found extending up toward, and in some cases reaching, the pelvic brim, and on these the fascia is carried.
