What is colles fascia continuous with?
- Scarpas fascia
- Fascia lata of the thigh
-It is a dense regular fascia
This is deep to the deep perineal pouch and it is only present in males

Is there a fascia layer deep to the transverse perineal muscles and external urethral sphincters?
NOPE!!
This is a potential space between the Colles fascia and the perineal membrane
