pubis to the spina ischiadica. Demonstrate that medialward 

 from the arcus tendineus fasciae pelvis the greater part of the 

 fascia is reflected upon the viscera (urinary bladder and rectum) 

 and venous plexuses about them as the endopelvic fascia 

 (fascia endopelvina) , and that other strands of fascia follow the 

 medial surface of the levator as far as the prostate, where they 

 fuse with the capsule of the latter organ, sometimes called the 

 fascia prostatae. English writers describe the fascia endopel- 

 vina as consisting of three layers, (1) vesical, (2) rectovesical, 

 and (3) rectal.

Diagram of the fasciae of the pelvis shown in a horizontal section of the pelvis. The fascia vesic. 

 sem., fascia rectovesiea, and fasria nvti prop, are parts of the fascia endoprlvina. (After Holl, in 

 Handb. der Anat. des Menscli. von Bardeleben, Jena, 18%, Bd. vii., T. 2, Abt. 2, p. 285, Fig. 34.) 



Demonstrate that the fascia descends deeper between the an- 

 terior ends of the two arcus tendinei fasciae pelvis and forms a 

 small fossa. (Cf. Fig. 279.) Isolate the prominent bands bound- 

 ing this fossa laterally, the lateral puboprostatic ligaments

 the bladder) ; in the female they are the /,/////. pubovesicalia Inf-
