 cavernosus, and it gives a branch to the bulb of the urethra. 

 Some of its branches enter the deep pouch to supply the 

 deep transverse muscle and the sphincter of the membranous 

 urethra.

which has been considerably exposed by the reflection of 

 the crura of the penis and the turning forward of the 

 posterior part of the bulb of the urethra (see p. 166), 

 will show that it is a strong fibrous membrane which stretches

 much in the same manner as the obturator membrane fills 

 up the obturator foramen.
