Fascia of Colles
Encyclopedia
The deep layer of superficial fascia (Colles' Fascia) is thin, aponeurotic in structure, and of considerable strength, serving to bind down the muscles of the root of the penis.
It separates the skin
from the superficial perineal pouch
.
On either side it is firmly attached to the margins of the rami of the pubis and ischium, lateral to the crus penis and as far back as the tuberosity of the ischium
.
Posteriorly, it curves around the Transversi perinæi superficiales to join the lower margin of the inferior fascia of the urogenital diaphragm.
In the middle line, it is connected with the superficial fascia
and with the median septum of the Bulbospongiosus.
This fascia not only covers the muscles in this region, but at its back part sends upward a vertical septum from its deep surface, which separates the posterior portion of the subjacent space into two.
It separates the skin
Skin
-Dermis:The dermis is the layer of skin beneath the epidermis that consists of connective tissue and cushions the body from stress and strain. The dermis is tightly connected to the epidermis by a basement membrane. It also harbors many Mechanoreceptors that provide the sense of touch and heat...

Superficial fascia
Superficial fascia is found in the subcutis in most regions of the body, blending with the reticular layer of the dermis. It is present on the face, over the upper portion of the sternocleidomastoid, at the nape of the neck, and overlying the sternum. It is mainly loose areolar connective tissue...
