A graphic representation of the interface between skin epithelium and the underlying connective tissue the reticular dermis. The dermis is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that consists of connective tissue and cushions the body from stress and strain.part from these cells, the dermis is also composed of matrix components such as collagen (which provides strength), elastin (which provides elasticity), and extrafibrillar matrix, an extracellular gel-like substance primarily composed of glycosaminoglycans (most notably hyaluronan), proteoglycans, and glycoproteins.

Most of us think of sleep walking or sleep eating as strange, but separate and distinct from obstructive sleep apnea, but a recent study showed that in a group of people with obstructive sleep apnea, almost 10% had one or more of the parasomnias (sleep walking, sleep eating, sleep hallucinations and paralysis, etc.).
Obstructive sleep apnea (OSA) occurs when a person' airway repeatedly becomes blocked despite efforts to breathe (see Figure 2). This breathing cessation is called obstructive sleep apnea. In cases where there are frequent episodes of both complete and partial blockage, the term obstructive sleep apnea hypopnea is used.
