Foreskin
Subcutaneous

The human foreskin is a laminar structure made up of outer skin, mucosal epithelium, lamina propia, dartos fascia and dermis. The superficial dartos fascia, formerly called the peripenic muscle, is one of the two sheaths of smooth muscle tissue found below the penile skin, along with the underlying Buck's fascia or deep fascia of the penis. The dartos fascia extents within the skin of the prepuce and contains an abuncance of elastic fibers. These fibers form a whorl at the tip of the foreskin, known as the preputial orifice, which is narrow during infancy and childhood. The dartos fascia is sensitive to temperature and reacts to temperature changes by expanding and contracting. The fascia is only loosely connected with the underlying tissue, so that it provides the mobility and elasticity of the penile skin. Langerhans cells are immature dendritic cells that are found in all areas of the penile epithelium, but are most superficial in the inner surface of the foreskin.
