7
Q

Deep layer (Scarpa's fascia)
8
Q

What layer of fascia of the abdominal wall is a thin fatty layer and is continuous with the peritoneum of the thigh

A

Superficial layer (Campers Fascia)

9
Q

What layer of fascia of the abdominal wall is a membranous layer firmly attached to the fascia lata of thigh and is just below the inguinal ligament

A

Deep layer (scarpa’s fascia)

10
Q

What fascia covers the anterior abdominal wall muscles on its anterior and posterior surfaces

A

Deep investing fascia

11
Q

Where is the location of the potential space in the anterior abdominal wall that can have fluid accumulating in it

A

Between scarpa’s fascia and deep fascia

12
Q

What allows for urine to accumulate in the space between scarpa’s fascia and deep fascia

A

13
Q

Once urine gets into the space between scarpa’s fascia and deep fascia, where does it go

A

It move superiorly

It cant move inferiorly due to the firm attachment of scarpa’s fascia to the fascia lata
