deep fascia
Last reviewed 01/2018
Deep fascia is a connective tissue condensation investing the wall of the body, peripherally out to the limbs, and around muscles. It is virtually totally fibrous and of variable thickness e.g. broad and with high tensile strength in the tensor fascia lata, but thin or absent over the rectus sheath.
The pannus adiposus lies superficially. Periosteum - firmly attached - or muscle - sliding freely - lies more deeply.
The deep fascia tends to derive its blood and nerve supply from the pannus adiposus.
Histologially, the deep fascia differs from superficial fascia.
