Superficial Perineal Pouch

Question 1

Site

Answer 1

Space between perineal membrane above and membranous layer of perineum superficial fascia (Colle’s fascia) below

Question 2

Boundaries: roof

Answer 2

Perineal membrane

Question 3

Boundaries: floor

Answer 3

Colle’s fascia

Question 4

Boundaries: anterior

Answer 4

Pouch is open as Colle’s fascia is continuous above with membranous layer of anterior abdominal wall superficial fascia (Scarpa’s fascia)

Question 5

Boundaries: posterior

Answer 5

Pouch is closed as Colle’s fascia (floor) fuses with perineal membrane posterior border (roof)

Question 6

Boundaries: on either side

Answer 6

Pouch is closed as both (roof and floor) are attached to pubic arch

Question 9

Applied anatomy

Answer 9

1. Injury of male urethra spongy part leads to urine extravasation into superficial perineal pouch then spreads into scrotum and penis
2. It can ascend in front of symphysis pubis to reach anterior abdominal wall or descend to upper part of thigh front down to fusion line between superficial fascia membranous layer and fascia lata
