It is lies between dermis and muscles of abdomen

Parts :

It is usually two layers

1. superficial fatty layer (camper fascia )

2.deep membranous layer (scarpa fascia )

But in children three well developed layers can be observed

1. superficial fatty layer

2.middle membranous layer

3. deep fatty layer

Contents :

1. blood vessels

2. lymphatics

3. nerves

4. in the groin superficial inguinal lymph node

Fatty camper fascia:

It contain variable amount of fat that partitioned by fibrous septum extending from the dermis with deep membranous layer .

It is continuous with the

Superficial fascia of the thigh

Over the linea alba

Penis as superficial fascia of penis

Scrotum as dartos muscle

Membranous layer (scarpa fascia )

In scrotum it is continuous as dartos muscle

In perineum it is continuous as colles’ fascia

 

Deep adipose layer

Thickness of this layer is more variable than the superficial fatty

It is thin or absent where membranous layer fused with bony prominence (iliac crest, pubis symphysis, linea alba,

It is thick in morbidly obese person

Its adipocytes show different metabolic activities to those in the superficial fatty layer

Liposuction remove fat from this layer

Superficial fatty layer donot remove to avoid skin dimpling and other skin contour irregularities
