Pelvic Fascia (Fascia pelvis). (Vide Spalteholz, Fig. 677.) 



The lower aperture of the pelvis is closed by the pelvic dia- 

 phragm, which consists mainly of the M. levator ani with a layer 

 of fascia above it and another beneath it. 



The inferior fascia of the pelvic diaphragm (fascia dia- 

 phragmatis pelvis inferior) has already been studied in the dis- 

 section of the ischiorectal fossa, and its relation to the obturator 

 fascia (fascia obturatoria) and the arcus tendineus M. levatoris

ani (0. T. white line of the pelvis *) established. The white line 

 of the pelvis may be exposed from the external side by removing 

 the acetabular part of the os coxae by saw-cuts (Pigs. 274, 275). 



'The German anatomists have misapplied the term "white line of the 

 pelvic fascia" to the arcus tendineus fasciae pelvis.
